The early leavers are terrible and can really take away the joy of the game. Its especially frustrating if you do your rank matches... and in 6b of 10 games players leave;(
I really hope Relic will punish this hard in a COH3.
As long as there is a reconnect button or a fix for bugsplatting. I assume a lot of players don't restart their games after every 2 matches and that may cause sudden disconnects etc. Imagine how frustrating it would be for new or average players to bugsplat or crash and get a leaver penalty.
I do agree leaving mid game should be punishable, atleast in ranked matchmaking for sure.
