I bought Crysis just to play this game and so far have been enjoying it, even though I suck...
It's a little tough jumping into a match 30 minutes in and trying to pick up enough points via kills to get into competitive mechs/vehicles but I've been defaulting into "support" roles for the team when I'm not in a front line capable unit (long range fire support, TAG, anti-air, etc..).
Battle armor seems a bit OP or perhaps has too small a 'hit box' based on their small size and the negative impact of server sync lag on targeting in a game like this. The training videos on youtube are nice but I wish a quick and dirty keybind document had been available (I created my own) along with some context help in game when you crosshair over an interactable object.
Impressive beta though, these guys have a solid product and I'm planning to throw them a donation as soon as their website quits throwing a 509 error...
