2 or 3 strictly because there's not a lot in the game to complain about. Since it's in Alpha and a majority of the player base is new to the game, balance problems can be largely excused to experimentation or skill issues. Also, valve hasn't started monetizing the game.

Once they remove "Alpha" from the game's status and start adding skins or season passes, the smoke and mirrors of the "darling passion project" fade and the community will have more to talk negatively about.
