Re: the most important suggestions by players !
Good offers, but let me disagree with matchmaking system remarks.
Surely, it's very bad one needs to wait 20 minutes to play 15 minutes. But you have already answered your own question
It's only because of lack of players. Battle sessions will start faster as soon as more users will join the game.
According group slots limit, I'm also disagree. That'll surelly be good for those who plays in team. But it will also increease disbalance allowing well played teams to put down enemy side that has no premade team.
Account level system looks nice for this game. Most users play more than one class. So it will be great their gameplay will cause some overall progress.
May be someone needs minimap, but it's difficult to use it because of fast gameplay. But may be it is useful.
Thanks for offers!
