Rustic you fool, where have you been?! Haven't seen you in ages...
Anyways, the game is pretty much t3h r0x0rs IMO. It feels very balanced, and I've never died where it hasn't been my own nooby fault. The game doesn't require as much shooting skill as PDZ, but you need to have good teamwork etc, all the obvious stuff really. You die in a couple of shots (one to the head), so it's very much a whoever sees who first kinda game, but that's where the teamwork and being able to shoot straight comes in.
If you play "one life" games there can be some pretty hardcore campers, so I try to stay away from them - I play mostly "Sharpshooter" which is basically like "Team Killcount". The maps are very big mostly, and the design is quite good for most of them, although they don't look anywhere near as good as the single player maps (which look like unbelievably awesome btw).
Grenade launchers are the only real problem with balance, but that can be sorted by using the "no explosives" weaponset. The MR-CLW (the gun that can shoot round corners - it has a camera attached to it) is also considered a little cheap, but you can choose to disallow that too. Apart from that I haven't found any issues with the other guns, as everyone has equal access to all of them.
The only thing is I'm not sure if you're connection would support this game - it needs quite a lot of bandwidth compared to say PDZ, especially on the co-op modes, and you have like 256 down or something silly, dont you? You might be ok with smaller games, but I'm not too sure about more than a 4v4...
Hopefully I'll see you online - how come you can't get on anyways?
