I know some abilities are meh, like Lux's W, but when you aren't using Cait or Jinx traps or Trist's leap or anyone's ult (I see this so much...I figure it's newer players saving it (I did that back in the day)), you are doing it wrong. Even the passive is usually important to keep aware of.

presses R, murders team.
It Hertz When IP6 votes presses R into R, no one trusts him and they all avoid, whole team dies as a result.
Catastrophic1 votes presses R on and then dies slowly as a result.

junglerboy168 votesCounterpoint to this is don't spam abilities needlessly when something else would do the trick, especially on a mana hungry champ.
For instance, if you have more than one strong wave clear ability, there's no need to spam both when a few AAs soften the wave enough for the first ability to clean them up, thus saving mana and a CD for harass or to keep your threat level up in case someone ganks your lane.
ABlueQuaker4 votesEzreal only using Q and no Auto-Attacks
Want to reform3 votesUgh, i've seen this all the way up in high plat. Players play him that way everywhere.
ABlueQuaker2 votesI mean, fair enough if you wanna attack from a safe range but in a full-blown fight basically use it as an AA reset (i.e. immediately follow an auto with it).
Want to reform2 votesOh i'm a Xin Zhao main, i know all about auto attack resets. I'm talking about the Ezreal players that play him like a pure caster, never ever basic attacking with him. It makes my skin crawl.
Its good advice though. Would help a less experienced player. (read: less nerdy than me)
Hella Kaiser1 voteswhat if i'm ap ez?
Sire Hippington2 votesyou still have ~100 base ad and can proc lichbane even when you miss the Q, and extra as from the passive Sure, you shouldn't take to much risks for useing your AAs on AP Ez, but if your close enough to AA anyway, you refuse to use some free damage if you don't AA.
Hella Kaiser1 votesif i'm spamming q as ap ez it means that i need to stay away. if it safe to do so i'll aa. but mine was a joke, so it doesn't matter.

KoKoboto2 votesThe difference between a Caitlyn that knows how to use Q, W and E in lane phase vs the Caitlyn that just thinks "hurr durr I'm playing Caitlyn free win"... I've been completely shut down as Quinn bot lane against Caitlyn, but at the same time have completely shut down Caitlyn's that have no idea what they're doing.
Anastaecia1 votesThat's a topic for another thread, but I always wonder about all of these posts about this champ owns that champ, or that champ (Cait/luci atm) is OP, etc.
THAT is only if the champ(s) are being played by competent people....many people in the game are not, and therefore trying to counter (even a hard counter sometimes) is moot in lower elos.
Chembaron Yamada2 votesSome time ago I was playing as Kalista adc with a Nami support.
We were level 8 both, the enemy bot lane jumped on me and I tried to get away as well as possible. But I couldn't help it and died. I then politely said to Nami "Nami, when they jump on me, please try to stun them with your Q."
My answer was a ping. "Q - not learned yet." Is that a thing? Not having put at least one point in every spell with level 8? ô.o
Anastaecia1 voteson some champs (with a very weak skill) or if you are testing a build,
but Nami should be getting her Q at level 2 or 3 (I flip flop between that and E depending on the matchup), no matter what.
Chembaron Yamada1 votesI can't think of any champ it would beneficial to postpone putting a point into a skill that much.... Except maybe for Udyr, since you are mostly chosing tiger or phoenix stance as your damage stance.
Because having another option in your kit is always an advantage.
Carl Grimes TWD12 votesI know some abilities are meh, like Lux's W
Lol
Silly Neeko1 votesEven though they seem meh they often are the ones that save your life in a fight lol, even if you dont max them, at least put a point into it lol
Want to reform2 votesThis. Janna's passive? One of the least noticeable and one of the strongest support abilities in the game.
Fighter and tank mains will understand the best.

Just Blame Jenny2 votesRight, which is why any halfway decent Janna player positions in the direction their ADC needs to kite.
Anastaecia2 votesOh, I know. I main supp and have saved quite a few ppl with Lux's W...it's just weak compared to her poking abiliites.
Speaking of passives...when I realized what Lux's passive did and started using it. OMG, big diff.
Even more so with Nami. When you realize you can speed your team up with any ability and you start using it, makes Nami the queen of peel over Janna if you play it right.
Silly Neeko1 votesYeah Nami has been one of my loves of support for a while now lol, im still fairly generalist but Nami...... She has everything you need in a beautifully splash arted package lol, especially river spirit! Its been one of my favorites of hers.
LadyRenly1 votesEven though they seem meh they often are the ones that save your life in a fight lol, even if you dont max them, at least put a point into it lol
some abilities I find just arent worth even putting a point into. I never skill Kogs E for example until level 13, unless my W was on CD, I just leveled up and I can secure a kill with it
Silly Neeko1 votesExcept even 1 point in his E.... Is that not his AOE slow? The damage is meh but the utility from it has saved many Kogmaw from my CC. He is barely stopped as he is using it, and it can slow an enemy jungler, along with enemy bottom lane...... Reducing or just about negating any damage you might take.
So at least one point is highly recommended.
Moonfall Saber1 votesDiana auto attacks....
Danjeng1 votes Let's go let's go! Five man ult into their team!
I don't level Ryze ult until levels 12/13, give or take a few levels. I can't really use his passive either. It's just there.
Sire Hippington1 votesImprtant note to that: AAs are part of your kit aswell. Even on a mage, if you can AA someone without aditional risk, then god damn do it. Especially early in the game your AAs do hurt, many midlane trades can be one by better use of AAs. And even later on, makeing use of your AAs as a mage can make the difference between someon lucking away with ~100hp and getting a kill.
Anastaecia1 votesyea, i was guilty of this as support for a long time...i'm still not great, but I'm a lot better. It's possible that reading Lux's passive closely got me to start doing it, so yay Lux.

passive is so...ugh
Fondling Gems1 votesReally? I find it to be incredibly strong, though I play Morg as a mid laner where the constant push + sustain power will shove anything that isn't named Xerath under turret indefinitely while keeping yourself healthy. With the hard CC and CC negation to walk away from any gank added to that and there really aren't any matchups she loses.
Morg can easily start pulling green numbers on her pool with just 3 levels in it if you get all the minions, which is pretty crazy honestly.
R181 votesIf you aren't using Cait or Jinx's traps, you are obviously gonna lose. While jinx's is maxed last, they are both essential for their success. HOWEVER, in lane, abilities like Old Kog Q and Sona's E are useless, as it is an inefficient use of mana. I think it all depends on the situation,
Carl Grimes TWD11 votesYou should actually max Caitlyn's traps but ok.
R181 votesI was referring to Jinx's. My bad.
RookPusher1 votesUseless abilities are what I refer to as the "assist makers"
