As a nearly dedicated Gal pilot and PS1 vet, I don't have a huge problem with the way Gals are at the moment, but I might be biased. I do think the gal spawn is a bit overpowered and can lead to some situations where it's nearly impossible to kill a gal that's got a dedicated stream of players coming out and I would prefer doing hot drops rather than just a quick landing, shields up and turn into a stationary turret while other people spawn from me. I think what they're doing could work well though. Sunderer turns into an AMS, works more like that. Galaxy SOMETIMES can work as a spawner, but I honestly feel that should have a decent cooldown on it for each soldier. I.E. spawn at a galaxy, can't spawn at that same galaxy for a few minutes. Give us bus drivers a chance to do more actual driving between the spawn points and the enemy. I forsee, hopefully, a group of 3+ sunderers with AA guns being a mobile field base, just behind a line of tanks protecting them. They form a circle where galaxies can land and get the full repair/(rearm?) effect from all three, load up the spawns from them, and take off again, all within 15 seconds or so if done right. In reality, it'll probably just be as big a cluster-*@(# as it's always been, but I would be happy if the rare organized group could pull something like that off.
Except for the HA LMG, most weapons are pretty darn good at ranges well beyond 60 meters... you just have to turn it off of full auto fire. I can be almost as accurate with a carbine and a scope on single shot as I can be with a TR sniper rifle. The medic's assault rifle is even better, but I rarely use it, so I don't have much experience to go by there. The LMG really is just supression fire. spray and pray you hit. You do get plenty of ammo to do that with though, and short bursts of fire can be decently accurate if you're careful and aim.
