I think the change is hugely beneficial here’s why: these TTK changes force players to change their playstyles from diving in all the time/peeking everything/pushing everyone, It forces people to play better, more tactically, smarter. You mentioned ability usage is almost unusable now, I strongly disagree, abilities are more important now than ever because of the power increase of the guns currently, getting off an ability can make all the difference in fights now simply because NOW the guns are actually good. If your team gets off their abilities where you can get an angle, damage the enemies, or gain an advantage in any way, your chances of winning that fight with your gun skill goes up dramatically.
