yeah I think if we are ever gonna have this kind of character that can completely alter an entire team's playstyle, we also need another character that can do something similar and also a draft system to keep it fair.
it wouldn't be a moba if it had low ttk, mobas don't work that way. it looks like ur looking for something more like valorant or cs. The tension in this game is not supposed to be split second snap aiming, rather mind games that combine movement, mechanics, and understanding of the game as a whole.
this is great, giving a definitive category to a character will make it too rigid and leave the impression that its the only way to play that character.
I'm chinese and I can tell you these are not chinese players, this post for example is google translated into Chinese from a different language because no chinese player talks like this.
they aren't going to fully port community characters but they definitely look at them for inspirations. on the item side of things both High Velocity Mag and Magic Carpet are credited as community ideas.
