Before the patch with new heroes, when quite few people were playing, the quality of the matches was good. Only occasional smurfs, but mostly the games were very well balanced and the teams were even. It's was hard and intersting to play.
Now many players returned or just got into the game and it's a big mess again.
As a totally new player I started as Initiate 1 and crawled my way to Arcanist 6. I had 50-game calibration before I was given my rank (yes, Initiate 1). Now my teams are full of these Obscuruses that don't remember or don't know how to play.
I wish the returning players had to go through at least 5 or better 10-game recalibration separately, not in the same teams as players who didn't stop playing.
It would help to better determine their rank/skill level, because now it's a mishmash of players who are very new and those who lost their high ranks due to inactivity and now terrorize the lower ranks. All the snowballs again.
I hope when open beta arrives there will be 2 modes again - competitive and noncompetitive (obligatory for a certain number of games for returning players).
