I like the idea this is centred around, and its easy enough to implement.
However, I think you'll find that there is generally a rearm truck at the airfield's western water edge, and if not, I would generally buy one for my jets...
CON:
Not relying upon team as much for protection
quick service = quick take off and preventing players from the chance of destroying you while you are taxiing
domination of the map = Rage quit/ salt
Diverting other players to airfield instead of focusing on missions and other objectives
PRO:
Entice the other teams to try and gain control of the airfield.
Faster takeoff/ rearming = domination of the map
It doesn't matter how you look at it... The jet is overpowered as FU in the right hands.
End result, We could sit here and argue all day about pros and cons but I think we will leave it the way it is for now.
