I am watching the live feed from day one and noticed there wasn't any sound that happened when a max was run down. I think it would be worth while to make some sound effects specifically for that, as I think it it's one of those 'planetside moments' that would be exponentially better with a 'crash, crash, crumple, crumple' when running over a Max, and a couple 'kerthump, kerthump's when running over softies, lol.
I suspect it wouldn't take a ton of time and would be well worth the effort in terms of game play...Those noises would be the lightning rod for the building anticipation you feel as you'e chasing down some helpless pedestrians!
Also, while we're on the subject of road kill; add the Sunderer's 'teeth' from PS1 back in as a cosmetic option in the store!
