Texture Issues and Weapon balance

Licence issues killed OA 0.8 and force me to retexture ctf_gate1 and ctf_inyard as I'm using his in the former map exclusively and two of of them in the unreleased improved version of the latter. As I'm not done with all the balancing and missionpack support of both maps I'm trying to give ctf_gate1 an equal look with given OA textures before I'm about to do new ones.
Although I've to state TRaKs texturepack was awesome.

Weapon balance: The nailgun which is typical for missionpack is the most beloved weapon of OA 0.8 but I don't feel good about it as for my taste it's overpowered most times. I need further gametesting on ctf_gate1 to see if I should add it in several gametypes. I shall post my experiences here...
