Okay, I've had this idea before, and I'm actually kinda of stealing this idea from a mod I helped create called Team Elite for a game called Star Trek Voyager: Elite Force. The mod itself was based off another game, Team Fortress, which I have never ha the chance to play but I would like to, but all this is beside the point..
The technician we created didn't do anything too special, he had the ability to put up forcefields as the original technician did for one of the game modes but the one I would like to see at least considered is the ability for Hotwire's and Technician's to drop ammo packs, seeing as they are already a support class, I think it only adds to they're usefulness. I also understand how this will affect gameplay so maybe it could just be added as a server side option. What I don't want to see is unlimited ammo packs they can carry..maybe like 2 or 3, nothing drastic. Just another idea I wanted to throw out there.
