o man, that's a doozy 
Good catch, longshotRumours
Possible applications: 5 generals send 80 minotaurs in to distract towers while 80 siege archers reduce citadel in...20 seconds? Or 5 generals just walk in with 80 priests and do it themselves, would probably take a bit longer but not much...Or how about you just walk in with all 240 units at once?
Of course until it was ready you'd have to keep your army hidden in the back of your base (Heaven's Wrath would 1 hit 80 bunched units, np) but I could see this being pretty crazy.
Actually, if you had a team of 3 assassins and two generals it would makes sense for the assassins to feed items to the generals to sell (even with the sellback as low as it is) just so they could build an army of grunts that actually go where you direct them, give no xp for dying, and can really jack up the enemy base pretty fast when you have 96 of them.
