New Runes: Riven Builds (Immune to CC and vs tanks build; Lane Trading and Scaling Build; etc.)

These will work well on multiple champs, not just Riven, example is Irelia as shown below with regards to this first build. I don't know how the tenacity will be calculated with the runes and their various effects (if they have diminishing returns with themselves internally as well as others), but on Irelia you can have up to 40% tenacity, 55% from this rune setup, and an additional 30% from merc treads. It says multiplicative, but I'm not sure if that same calculation is being applied with the runes, or how they combine and interact with each other. There is 20% from one rune maximum, and 35% from the other. This is an aggressive, tenacity focused build that works well against tanks, bruisers, and similar targets with high amounts of slows or CC. It does decent damage, while offering fair survivability through the CC resists and passive healing from second wind.

I should correct myself, technically you're not immune to cc, but say as Riven, a 3 second stun becomes a 1 second stun, a 1 second stun becomes just over a .3 second stun. You can even go further than what I suggested with a Sterak's Gage on top of this, to almost reach the level of Irelia on a regular champion, and essentially CC just slides off of you.

Yes, this first CC-resisting base build does not include Sorcery, this is intended for use against team comps like Morg, Thresh, Gnar, Fiddlesticks, and similar champions or groups of champions that will essentially remove you from the game. What you lose in raw burst (as compared to Electrocute) you gain in sustained damage, and the ability to become almost immune to CC (so you aren't completely wiped out of the game), you may still need to buy a QSS (if vs WW or Malzahar for example, or champs with severe knockups (which aren't reduced by tenacity), but for the most part this will allow you to stay relevant in situations where you would otherwise struggle. Altogether it adds to be an extremely potent build centered around having a solid game, while cementing your weaknesses (CC; as with any champion). The burst build will hit harder, and will carry harder, but it would be ineffective against coordinated CC or concentrated CC, whereas this build allows for you to in large negate these effects. You sacrifice free lethality, AD, concentrated burst (electrocute), good sustain and hp increase stacking (undying grasp), and of course better lane trading (comet; has shorter cd than electrocute, gives 10% cdr while likewise offering good scaling and stable stats, very good throughout lane phase and into regular game). Yes, you lose the heightened damage potential but instead gain the ability to be far more slippery, while still maintaining sufficient damage (+3-9 AD per auto you weave, in addition after 3 autos gain +12% increased damage to that target), gaining an overhealing shield like BT, having the sustained increased damage per takedown if you get a good teamfight off you can gain large amounts of bonus AD for the duration of it, definitely deciding close fights, and also get the important ability to initiate without fear of being instantly negated by hard cc. The laning phase is rather decent, and this build is best against any team comp in which you would fear being locked out of fights (but in which you are still required to frontline for your team).

"If the runes are calculated together additive, and the rest is multiplicative, that would still result in 19% effectiveness for the CC (81% resistance on say Irelia; 55% from Runes, 30% from boots, 40% from passive; 0.45 x 0.7 x 0.6; if individually it would be 0.65 x 0.8 x 0.7 x 0.6 Runes, Runes, Boots, Irelia = 22% effectiveness, 78% resistance). On a Champ OTHER than Irelia that would be 0.65 x 0.8 x 0.7 = 36% efficiency, 64% resistance, which is still amazing. To my knowledge Knockups and Suppressions are not affected by this reduction.

Again I'm just not sure how they're going to calculate it for Live."

Above is my comment w/ the calculations (or approximations of)

Ultimately the build I'm showing here would work very, very well on champions like Riven, Fiora, and Irelia, who are divers that will likely absorb significant early cc. This build would synergize well with Riven for example, as you continually weave auto attacks in (and the extra 12% damage increase after 3 hits), overheal is good for obvious reasons, the tenacity option is taken for equally obvious reasons, and then there is the Coup de Grace, it works exceptionally well on Riven's ult, and more importantly since the secondary effect stacks, you become increasingly powerful after every takedown within the timeframe. The Summoner Spell part would be used especially on Riven (you're likely to flash in at some point, and teleport will have likely been used as well). And the 4% healing is great for laning (and even afterwards for some minimal sustain versus harass, or clutch healing in general).

There were other builds I was considering, (also uploaded on Imgur with it), which included Comet (short cd, good for lane trading and outside of lane is not bad either), Ultimate Hat (shorter cd on ult), Transcendance for 10% cdr, Gathering Storm gives good scaling AD the longer the game lasts, Sudden Impact for the bonus lethality that is pretty much permanent, and eyeball collection b/c it gives AD + lethality. This build offers good scaling, while functioning well as a lane bully, and gets better the longer the game lasts.

This would be the more bruiserish survivability based build, it's weaker early, but generally has better sustain (and the keystone works well as your are constantly trading as Riven). The goal from it is to gain extra HP stats while being able to transition build wise into either more offensive or defensive (BC/DD or lethality build; both work well, extra survivability for the Lethality build, while becoming even tankier for the alternative build). Undying Grasp for sustain in lane, as well as the stacking HP passive, Perseverance again for the extra tenacity and slow resistance, Conditioning for bonus resistances, and the extra healing after trading (if done properly you will only heal from trades if you block all of their damage with your shield + undying grasp healing + gaining extra HP from these trades as a result), then you take Ultimate Hat again (you always want your ultimate up as fast as possible on Riven), and Gathering Storm for the bonus AD the longer the game goes (to keep you scaling despite not being as offensive a build as the others; transcendence is viable here, it would give bonus CDR, I just don't think it's needed as much as extra AD).

The final build is the most snowballiest of them, but offers less constant laning pressure and trading than the others (which is why I don't personally like it as much; electrocute has a high CD). Electrocute of course deals exceptionally high damage, and scales very very well with full AD lethality Riven, if you get ahead or get a free lane (vs Nasus for example), and snowball off of that lead. It works very well when ahead, and will be extremely oppressive to play against (this works for pretty much any assassin too). Sudden impact again for the bonus lethality whenever you press anything (pretty much), eyeball collection for the bonus AD and lethality, Ravenous Hunter is not AS good as it could be (all of her abilities are AoE so it's reduced) but it still offers a fair amount of overall sustain and can be great in teamfights where you are hitting multiple targets at once (and goes well with a Death's Dance). Ultimate hat and gathering storm are still the best options here (Gathering Storm keeps you relevant and allows you to even better use the free lethality the longer the game goes the more deadly you become).

For the most part it will be dependent primarily on player preference or matchup, I wouldn't take the Domination build against say Gnar or Darius, I'd likely take the Undying Grasp build for those (more HP and sustain). Vs Tank matchups the Precision build is the best (despite the attackspeed being a wasted stat, the extra AD (especially the longer the trade goes, by far) from the keystone (Press the Attack) would help a lot, it gives you tons of tenacity and slow resistance to keep up with the tank while running them down, and helps you regen from the damage they deal, the overhealing shield is not bad either (as you'll usually want to take a Death's Dance at some point along with Black Cleave to shred and sustain against them). It's an interesting set of options you have available, that can be individually tailored based on preference or matchup with ease to become far more efficient. Each build has it's own peculiarities and strengths, along with of course weaknesses.
