Repair bays would be easy to destroy because they need everything to work to repair a mech. so just a couple hits from something small would kill it.
IMVVHO
then why have them then if they'd be so easy to take down? ... you'll end up with this for EVERY MISSION
force commander to team
"Ok aerotech guys, take out the repair bays first"
and this would be the first thing done every time, and it would be taken out every time if they would be so fragile...
please don't make them so fragile...
thx
