uhhh you're just wrong lol, Killjoy is played on pearl as of recent and also on haven by multiple teams.
Cyphers buffs will make him more viable on breeze and more viable on other maps like possibly ascent and haven again
the chamber nerfs are supposed to be like pretty big bigger than the ones before, they still have not nerfed his ultimate firerate and headhunter pull out time which is his biggest fucking issue.
I asked for if yay would be the main sentinel or go back to jett, and I assumed he'd go to jett obviously.
Zellsis and Xeppaa on sova like i said do not look like a top tier sova, but it is obviously because they are not comfortable on those characters, I think that c9 probably have thought of an issue for the sentinel problem but when you have two duelists and two duelist flex plus controller igl it just doesn't make sense role wise.
I think 100T NRG will be over c9 for this year but I do think c9 has incredible talent, its just NRG and 100T have the roles making sense.
