I'll just say this. I have a friend who I would say is an exceptional player. He has latency issues, but deals with it by learning rotations and counting down to seconds then move, without relying on the markers/cast bars being shown on his screen. If it's easy for you with close to no latency issues, great. But asking for fights that include 1HKO mechanics to happen randomly when the casts happen very quickly would kill off a large portion of players.
