Actually I'd like for re-arming to be possible only inside the hangar.
As it is, I can take a Sulla out, drop some Tbolts on an unsuspecting Partisan, afterburn it back to base, re-arm in mid-air without any difficulty, drop another two tbolts... rinse and repeat for the desired effect. All in the space of a few minutes. It shouldn't be nearly that easy for me to pack so much damage in such a short space of time. The same applies to any of the bombers, assuming I make it back in one piece. Aeros can really be abused this way IMHO.
If you consider the amount of ordnance I can deliver in a given space of time depends on distance to target from airstrip, enemy armour just outside our own base don't stand a chance, providing friendly mechs are otherwise engaged.

I'm thinking this could be a problem in light of other game modes?
