Well the problem I'm seeing is this, I was in a situation a couple of times yesterday where my heli was damaged and I bailed out pretty low to the ground and survived, my heli which while in the air was burning and at 12% health had landed next to me fire out and immediately was already repairing itself. The second time it happen was virtually identical hit by a heatseeker from another chopper and I was able to do the same thing and get back into the heli while it was at around 20% and fly along like nothing had happened.
You'd think it would have to be repaired to around half health at least for it to be flyable, and whys it start repairing itself as soon as you bail out anyway? They just seem to have ratcheted the vehicle regen up another level and if you can bail out from a lowish height and keep the chopper fairly level while doing so it seems to just float down beside you and start regenerating on the way down. You'd think you would have to bring it upto around 50% or thereabouts for it to be flyable and need an engineer to do it. As it stands now it seems like the Engineer is optional and critically damaged choppers seem just as effective as fully charged ones.
The repair mechanic just seems to have been dumbed down even further.
