We tested it out on Sunday and driving APCs was interesting enough. It doesn't sound like fun, but if you've played any survival horror games where you don't get any weapons then you get the same feeling from driving an APC, LOL.
The low tonnage is because heavy weaponry tears through APCs super fast. I don't want a pair of Scat B's MASCing in and blowing up the APCs before anybody even notices.
Yes flying things get a major advantage, that's why it's restricted to BV 1 aircraft that are 30 tons or less (Hawkmoth, SparrowHawk, and Donar). In that way they serve mostly as scouts and are unlikely to be able to kill very many APCs before they get to their final location.
We could ignore any metagame effects the escort missions and just play them as interludes between matches. I wouldn't have a problem with that. If it seems like it would be fun, we can integrate it. Either way is OK with me.
