Accuracy while moving has been substantially decreased the TEC Mod encourages a much more conservative style of play (taking cover, shooting from around corners, getting the drop on enemies). Don't expect to be able to shoot on the run. This Tactical Enhanced Combat Mod decreases the 'ego-shooter' factor of SWBFII and adds to the 'oh-crap-if-I-leave-this-cover-I'm-going-to-die' factor, which is nearly non-existent with the regular game. With this huge mod, running blindly at even a measly battledroid is going to get you mowed down.
Supposably being a normal trooper? Well, no longer, Sparky.
