Boards has it wrong, CC is honestly more of a problem than overall damage (please implement DR)
I'd rather be one-tapped by
or
than be chain CC'd to death due to being hit by ONE singular CC. At least when I get oneshotted by a champion I can move on with my day and be like "Right, I'm dead, that's that.", when you're chain CC'd you always have this constant hope that you'll live.....but then you get hit by another form of CC and/or insta-die.
Nothing is more tilting than being hit by one rogue form of CC and dying off of it due to being hit by MORE CC, and all of that CC is likely to be back up in the next 4-8 seconds due to the ease of access in terms of CDR. As such I believe that this game needs Diminishing Return. If you don't know what DR is it essentially means that if you are hit by further CC the effects diminish over time, so you can't be CC'd for over 5 seconds unless you get hit by like 7 CC abilities.
Damage can't exactly be done by a lot of champs unless their CC ability hits, so as such CC is more of a general problem than damage right now. Obviously look at both, just PLEASE look at CC since there's been an immense increase in the number of CC in the game.
