My opinion is split here. On one hand, I love to GV and think it would be a lot of fun.
...BUT....
Adding air support/defense will just make for easy GV kills. One life events would be quick due to the ease of killing a GV in the game with other GVs. One shot, one kill most of the time. It would be a jousting match with lifespans cut very short.
I thought about allowing only a small amount of fuel and ammo for GVs then enabling a C-47 squad to deliver supplies to the front line. These supply planes could be guarded by a fighter squadron and attacked by another fighter squadron. The drive of the attacking GV force would be metered by the success of the supply squadron and escorts getting their jobs done. Maybe a three life event for C-47s, two lives for GVs and single life for fighters.
This, of course, is my personal opinion and does not reflect the opinions or future plans of the Aces High CM Team or Events staff.
Still, very much a worthwhile discussion.
