I think that matchmaking is quite good now.
One big problem imho is that people don’t try to play at least 2 classes.
When i see a match with 3 dh against 3 necromancer or 3 thieves and none of them switchs .. .i think the problem is of the player. Class stacking is and can be a problem but for example, if i queue with auramancer and i fall in a party with one or 2 already ele, usually i do one of the 2 things :
– change my build to freshair marauder
– switch to something else ( i play ele, scrapper and chronomancer for most based on team composition ) .
I am in silver and switching i have to say that i am able to stay around 50% of win and not having great losing streak
