As
@Sponsor said, we were running only 2 discs and ran into a ton of premades (mostly not noteable ones) but the ones with even more discs we absolutely demolished. People are focusing too much on solo queue right now, if you want to solo queue yes you will lose to discs, a lot. But if you even have 2 competent partners and one of you is a healer, you can kill almost any of the discs. Me and maestus of sponsorz were going 2v3 or 4 sometimes against all discs, most don't heal eachother and you can just burn them down 1 by 1. A vast majority of the discs you will see and fight are going to tunnel vision for meters, that's their weakness.
Tl;dr - disc is op ye but don't solo queue if you want to kill them.
