Mobas are always prone to snowball.
Main issues currently imo.
Smurfing is highly negative in 2 directions. They want to sink? They try to force losses. They want to stomp, they brutalize people. To float in a MMR requires intentional effort to not win games so they can maintain a skill advantage to pub stomp.
Duoing MMR range is fucking massive. Its off Rank not MMR so fringe cases between division 4 and div 2-1 of the rank above cover a huge range of playerbase.
Idiots on NA give up to fast for no fucking good reasons. Honestly my main complaint about the game is how quick folks are to stop playing or the garbage reasons they give up. Bruh I don't fucking care your losing lane. Just play safe and let the rest of us carry ya. Your team (hypotherical you being a hypothetical teammate not @ you as a person) are up massive leads in both obj and kills ffs please don't AFK. -insert 6 min of gameplay latter- actually fuck that please afk and stop running it down mid you fucking child.
High uncertainty games are low quality. that's honestly unavoidable with a 24/7 que with population size changes.
People forgot you need to be able to play multiple roles/champs and are an Instant handicaps if they get filled or their main gets banned.
People forgot WTF a balanced team comp looks like. Yes
is gonna be a great comp into a balanced comp with HELLA hard cc.
