While this game has its moments I honestly can't say that I'll buy it.
The support class seems fairly useless as its gun is too inaccurate and/or doesn't do enough damage when you do hit something, and it's tripwire mines also seem pretty bad as, in my experience, they'll only do 90 damage to someone standing right next to them when they go off.
The medic class, however, seems pretty good as I imagine that my minor issues with the accuracy of its guns will be solved once you can customise them and add scopes and various other features. With that said, as I've been playing with randoms for the past couple of days can I just complain about how terrible everyone is at staying alive long enough to be resurrected? I'm guilty of doing this as well, but I've only ever seen one person request to be resurrected in the 4-5 games I've played as a medic as every just holds down the spacebar to get back in the fight ASAP. Making your game designed around cooperation and coordination is a bit of an issue when everyone on the server has the survival instincts of a particularly dead lemming and the cooperative abilities of a housecat. Other than that it seems like a decent class and running with a proper squad should solve most of the issues I've seen.
Assault, meanwhile, is a very good class, though I don't know why they gave it both AT grenades and TNT. I mean, sure AT grenades don't seem to be that great, but I don't know why they'd double up on AT weapons like that. Speaking of which, AT weapons —aside from the emplaced ones— seem a little-underpowered considering how easy it is to get a tank up in someone's face. I mean, what are K bullets even for? You get 4-5 of them and they do tiny amounts of damage. Are they for dealing with light tanks and armoured cars? Why is TNT a better AT weapon than AT grenades? I mean, sure there's a risk versus reward factor given how far you can throw AT grenades versus how far you can throw TNT, but it just seems weird that a dedicated anti-tank weapon should be less powerful than a more general purpose item you can use to set up traps. Also, why does the AT sniper rifle powerup only do 11 damage to tanks? Like K bullets, is it supposed to be used on light vehicles?
