Solo/duo queue needs to exist, that way both sides are absolutely even. I swear I go through 20 matches until someone calls out. Before anyone says go do FFA, I did, I got champ preseason. My snipers playlist is the only one I powered through hell because I played H3 snipers a lot so I knew that was an easy champ. However I had a 40 wr for a long time, eventually got a 60 wr by the time I was champ, but most teams I met had a 85-95 wr, yet I had the #5 highest kd/kda/kpg according to Halotracker. I’m not saying make every playlist solo/duo just make a playlist with that option. My arena placement I went 3/10 coming in first probably 6/10 times, but still got Onyx, I went against the same team 4 times in a row that were ranked 1750, I was 2-2 against them because they only win as a team, if I had a team they would get steaked, if they were solo queue, they would never win.
TLDR: make solo/duo queue happen for one playlist
