::Banshees when idle point their jets in the wrong direction.

::One of the dragonfly's fans does not turn.
::A lot of gunships turn and face the opposite direction that they were moving in once they stop. It's annoying when trying to take screenshots but could also prevent them from firing immediately should an enemy come into range. IMO it looks kind of derpy but could work for a landing animation.
::A lot of the (aircraft and other) fans sometimes produce jittery animations, which I suspect is related to vsync or the lack thereof.
::Brawler's fan should probably point at the ground when it's idle hovering. It should only point backwards if the unit is moving forwards.
::I think rocko and storm's projectiles have a higher velocity than they do in BA. I'm only basing that on videos since I haven't gotten around to testing out original BA quite yet, so I can't confirm it, but I will soon. I suspect there may be some scaling issues due to changes in unit size, but I'm not sure how much of that is merely apparent or what sorts of things affect unit presentation in BAR.
