[Suggestion] Boris overhaul idea

Playing devil's advocate for sake of discussion.

Giving specialists vehicle 'buffing' abilities is tricky.  None of the current specialists currently offer any sort of vehicle buffing ability*.  So you can be certain if a specialist offers some sort of vehicle buff all the vehicle mains will use that specialists.  The buff provided by the specialist now becomes a sort of global buff for all vehicles.

I can see a few metas developing for a deployable repair station.

• AA Tankers - These guys are generally stationary most of the game anyway.  The driver would get to their campground, hop out, deploy the drone, hop back in.  The extra repairs might make these guys tough to kill.  
• Tankers - Similar to the AA tankers I can see the more passive/defensive tankers plopping a repair station near their campground.  Take a few hits, then retreat back to safety for an accelerated repair and then back into the action.  Tankers playing aggressively would be at a disadvantage if they ever come across another campy tanker supported by a repair station.  I think Battlefield plays better when aggressive tanker play is encouraged. 
• Fast Armor (Bolte/EBLC-RAM) - These players generally rely on hit and run.  They could plop a repair station down somewhere along their 'recovery' lap route to shorten the time spent away from the action
• Heli's  - Although I understand there's problems landing Heli's at the moment I could see a similar tactic as the fast armor.  Pilots could deploy the repair station in some remote location or on top of a building.  Make this part of their recovery lap for extra fast heals.

I guess the obvious solution to those problems is to have the repair drone de-spawn once the owner enters a vehicle.  But if that's the case would anyone give up their gadget to help a campy armor player?

Another thing to consider is how stacking repair stations would work.  If an AA tank had 2-3 repair stations nearby could they out heal the DPS from an attack heli?

Also Transports/Heli Gunners - If someone intends on spawning into a transport or heli gunner seat choosing Boris with his newly added gunner buff would be a no brainer.  I suspect most vehicle gunners would be Bori which results in a sort of global buff to vehicle gunners. Transport gunners have seen a lot of nerfs lately - are we ready to see them indirectly buffed by a specialist ability?

*Irish's sentinel seems like it'd offer a good synergy for campy armor players, but I've never seen it used in practice so I'm guessing it's not that great in that application.
