Poor weapon balancing in TDMs-I remember this one guy's server, he's recreating a Counterstrike map.
Map was brilliant, guns were NOT.
Sgt Walters BF3 pack, the Old-ass L4D2 pack, and even BKT and T+T to throw in.
It just ticks me off to a degree when I see that in ANY tdm, I mean...
Good Grief.
Also, messed up builds, like 1x1 walls, or areas where 1 or 2 bricks Should've been used instead of 10 or 20.
