Don't really have a problem with the Fixed vs Gimballed much. Except that NPCs are deadly with fixed and seem to spam chaff quite often. Don't know why you need to nerf the gimballed weapons tracking, though since then can be so easily countered with chaff. I've found that a number of times I've had to unlock my target and use my gimballed as fixed.
Guess it's time to start putting large PACs on my Python and Corvette again. I actually miss those, and with rapid fire mods.
Power play, don't really care.
The RNGineer part is what seems to get to me the most. Tweak the attribute value, great. Remove attributes, not ok. Add attributes, then auto roll for players who already have the mod, definitely not ok.
