Logic of Riot...
Yasuo turns OP on 1 and 1/3rd items. Rabadons cost 3.8k gold(Spike in AP stat) However Before rabadons cost 3500g, if you got rabadons as a 2nd item, you only got around 70-80 bonus. Lets look at the stats vs gold. 120 AP flat, 35% bonus AP, but it cost 3500g 435g = 20 AP x5 = 120 435 x 5 = 2175, + the 70-80 bonus AP lets say 80, thats like 4 extra amplifying tombs. 3915g total AP bonuses for 3800g. Hardly worth the investment. Rabadons is a decent 2nd or 3rd item for its cost at 3500 last season. Now its a decent... 4th or 5th item probably should not b epicked up anytime before that. What I mean by "item" is big items like Rylai, Zhonya something that gives 70+ AP not boots... then it becomes a worthwhile investment for gold costs. Yasuo turns OP at 3.3k gold though.
I hate to be a complainer and a QQer but seriously this is fucking stupid. This is just idiotic logic. If someone was high on meth and injected marijuana into their brain directly I would understand why they would make these changes... the person is retarded obviously but they actually hired people, to make these changes. People get paid a high salary from a billion dollar company to make these changes. This isn't a small time company that just started up out of college where you'd expect them to make large mistakes.
Tanks have been strong last season, and a lot of people didn't like the tank meta, but atleast it was balanced in the sense that, HEY late game a tank can't really kill an adc, an ADC with lifesteal could just shred tanks or avoid them completely, but Riot rewarded them with a decent clear in jungle, strong CC, and low cost tank items with masteries that supported it. There were also no items that cost 1300g that gave 10% bonus dmg, or 1300 gold item for 30% bonus armor shred, which also tier'd onto more powerful items for 2700g. The gold is very important to note. The same reasons that made Tanks really strong. Damage items are expensive, tank items are inexpensive, now they fucked it all up. Tank items costs a lot of gold now, and the armor shred/health shred items/grievous wound items are 2700 gold... the price of the old spirit visage.. A TANK ITEM that COSTS LESS becuase its a FCKN TANK ITEM. Now DAMAGE ITEMS are low cost. Good luck mundo .. Good luck.. 2700g counters you FUCXKING HARD. Heal reduction, armor shred, health shred ADC's choice. Might as well run 2 ADC's 1 at top and 1 bot. Cuz who the fuck can counter the ADC at top now. If yous tack armor or health cuz you're in a losing lane, they will counter you with superior low cost item choices and snowball harder. Like does no one actually realize the depth of how fucked up it is? A lot of people realize the very obvious imbalances of yasuo, and masteries for shitty AP's and the higher cost of AP... but Tanks and bruisers are supposed to counter ADC's now, or atleast lock them down or kite.. but now ADC's are so fucking powerful and tank junglers are so weak(150% mana regen fucking sucks stfu.) that now they don't even scale well. And to compound the problem the anti-tank items are 2700g... lower cost than actual tank items LMFAO. There are 2 ways to devalue tank stats, thats cost of the items, and enemy counters to your tank stats. Riot nerfed BOTH of that. AND Buffed ADC's. And removed crit reduction mastery AND just overall made tanks a lot more shitty.
THis is so illogical I bet pro teams are going to FUCK you guys hard for doing this many changers, changes are going to be made very quickly when they realize the state ADC and tanks are in. Atleast late game old patch adc's could counter tanks, now they counter tanks all game. Tanks are almost obsolete. might as well just keep them for peeling for your adc. (Kogmaw much)? can't even play APC now... for the same stats they greatly increased gold costs (Zhonya is 3500g) the only AP + Armor item in the game is nerfed. and ADC's are buffed so even n ow ADC's have advantage on APC now in terms of gold vs stat values.
