Quite a few things feel rather awkward, the re-spawning defenses got me, didn't actually realize they were mannable though. and I don't know if this was just me being unobservant, but the AGT didn't seem to stop SBH's wandering into our base constantly for nuking. Might just be that everyone is insane at wall hopping now.
Vehicles seem to slide around more than I remember too, might have been the server but you would never believe medium tanks had tracks, looked more like ice skates.
Planet side just finished.... might check it out in a bit.
