The more crowd control there is in LoL
The more necessary high mobility, high burst, range and tankiness become. And the less relevant DPS and active mitigation are. Basically you have to either survive the CC, avoid/mitigate it through mobility or have the burst to do your job before being locked down for 10 seconds straight.
Before people start talking about high mobility, ranged inequality, burst and tanky damage dealers. They need to consider the fact that the alternatives are not relevant for a reason. They get crowd controlled, and suddenly have 0 power.
