Good one... A single airstrip won't up 60-80 buffs, times 3, in 5 minutes...
Bigger problem is for snapshots, FSO's and scenarios - trying to limit how many "buffs" can take off from one field would be a total pain in the neck.
Same for hording, how do you limit how many planes take off from 1 airfield?
Its possible, however I think if HTC would of had an answer to this it would of been delt with long ago, except the hordes have changed just about every few years.
First it was a dozen Me110s and a few goons.
Then it was a dozen Me110s, few fighters and a few goons.
Then it was a few Me110s, bunch of 4 engines and a few goons.
Then it was a few fighters and few 4 engine lancs with a few goons.
Then it was 4 dozen fighters and a few goons.
Next will be "Vote the NOOOOOOOOOOOOOK!" with one B29 and a dozen goons.
After that I am guessing 5 years from now "Nuclear Submarine to n00k town" with a few goons.
I will still be drinking a beer saying "Dude when did they add nuclear subs? last patch? since when?"
2 Years later I will still be begging for the horde to let me "dogfight someone 1vs15"
Same poop, different patch.
