I've now played a few 1.3 games, and been impressed with the overall stability. No major bugs or crashes to speak of yet, but I did notice a couple of things.
Pilots do not take on team colors...can be confusing when deciding who is heading for that freshly sniped turret.
Forward speed seems slow in hover units. This is doubtless due to the correction of the side thrust speedup thingie. Can be a bit dull traversing the map. I'd suggest that to compensate, top speed and accelleration be bumped up a bit to preserve the sense of urgency of the game.
