Would be good.
I think its a good idea to give us more flying than firefall, like a recent big game
Especialy for light mechs, perhaps ablility to fire at ground targets with bonus dmg when in the air.
It could be a good way to make mechs feel different.
But time in the air should be limited and dont overcomplicate by making it a specific skill.
I also think mechs need a bit more speed in the air, not strafing exactly but while going up and forwards.
