NGL but OW1 from 2016 was not casual, at least not like casuals are now.
At the moment, my experience tells me that people in rank nowadays are less competitive than back in S1-S10 and people in QP are more competitive than those seasons.
Its very weird how “normalized” the curve has turned to be. The worst part is that for some reason, people that should be Arcade (because they rage quit like theres no tomorrow) populate unranked instead, turning it into a chaos mode where legit players can’t play 10 matches without having at least 1 leaver in 8/10.
