Gun spread is bad enough as is. It's also sci-fi... none of the armed forces on the planet have to deal with soldiers who have personal recharging shields or can aim as they're currently being pelted by bullets.
Personally wouldn't mind seeing you lose aiming capability for a split second if you're in the process of being shot. Otherwise, probably fine as is.
The head is decently hard to hit unless you're using a sniper rifle and decently close and they're standing still though. Maneuver is still almost always the best option. Get into a position to surprise them rather than try to duke it out face to face unless you know that won't work for you. (You're in a MAX or they're Light Assault and you're not.)
I happened to be in a relatively epic fight last night before bed. I was TR on West 02 and we were as far up as Dahaka(sp?) before we got held back by concentrated NC defense(and a bit of VS just being dicks because they didn't have any territory anywhere nearby.) We took Coramed labs, got it spawning people, I was flying a gal and move a bit north, took another surrounding base and finally moved down west of Dahaka and took one of the gateway bases. The gal didn't survive too long, but it was long enough to spawn about a dozen troops there and give us a strong push. Unfortunately a couple of tanks and some max suits stopped the push. Air cover was terrible and they had a lot of turrets nearby so we couldn't get any ourselves. We held that base for nearly an hour, defending from galaxy drops to the north and west, having to retake coramed labs numerous times. Vehicles crossing the bridge and climbing up the valley wall all attacked us including a convoy of sunderers. We finally lost both that base and Coramed when a serious push of at least half a dozen maxes and a dozen other ground troops swarmed over us. We didn't win, but it was a good fight and definitely the largest scale fight I've done so far. The AA streaming overhead. The occasional fighter swooping over at rooftop level.
My computer stuttered a bit, but not as bad as expected and except for getting a few nice rocket shots on the tanks and maxes, and one really silly lucky rocket against a light assault that landed right in front of me just as I fired, I wasn't able to do much other than run around, spraying bullets in a general direction and capping bases. Tried medic for a short time but found I was a constant target of snipers and since we were fighting in and around spawn points, nobody really needed reviving.
