@Palette24carats in my opinion you and
@Cheese9Man can't compare ALGS with ranked or public games most of us are playing daily.
ALGS require one set of skills and they are on a totally different level - none (a few) use Revtain combo there, not to mention that no one dares to jumpad the whole team into close quarter battle after first hit shot from the distance.
Ranked and daily gaming - people are just sick of players who let's be honest possess close to 0 skill yet over and over again (again sure due to various reasons particular team is playing not ideall) get away with pushing gun into your face and landing 3 shots with Wingman or Eva or a full mag of R-99.
Here is one video I have (hope it will not be removed given I am not shaming the person, just using this gameplay as an example + being lazy to cover up the name) -
https://youtu.be/6kP_JrBDr1oA clear example in my opinion of what most of us associate the term "controller player" with. I hope I don't need to analyse this video in detail to point out all aspects of it and you will get/understand what I am talking about here just from watching.
