The MMR gain/loss is too large in blitz - results in too large skill differences which cause frustrations

yeah that’s the biggest problem. When i play my main at 2800 cr, 3k mmr i often see 1-3 players from 1700 cr who are doing very poorly and having little idea what to do which often results into bad games. Meanwhile when i play my hunter in green gear, which i created 3 weeks ago and never played hunter before i often get matched into 2800+ mmr games just because i got lucky to win 2-3 games in a row. People often flaming me for doing low dps while i can’t even understand what iam doing at this mmr with my new class lel
