[@Irredeemable] My hesitance to allow vehicle pilots is because by their nature they are going to be removed from the rest of the group during gameplay. And unable to move ahead with the group in certain situations and scenarios. 

Even if I separate the Driver and the vehicle, then the player will probably question why they are playing a driver.

The Sentinel is the only vehicle I can think of that has the best ability to keep pace, keep with everyone else and follow the platoon into tighter areas that a tank can't follow. but it still has its problems but its preferable to a chimera driver, who would probably just get bored after awhile.

Its good to see a swath of new people though. We definitely have enough bodies that I am more open to allowing an auxiliary or two.
