Define 2 'full' accounts. If you are talking dumping 250 Carriers in 2 minutes yes. 12,000 deploys will require 47 gold refills which given the ingame lage is not possible. Then factor in the required 100 deploys per second to reach that amount in 2 minutes and it is highly unlikely by just tapping like a banshee.
If you did 12,000 deploys in 30 minutes that would be 6.66 deploys per second but then you would loose time to pop ups though perhaps they stop at a certain point but also to the 47 gold refills required unless there is some way to increase your max deploys from the default 250.
Oh crap wait a sec, since I don't buy gold or use refills, that gold refill isn't to full top up all 250 deploys is it..... Can't remember what the number and is so that would be 47 x Xto top up all 250 deploys. So it's starting to seem rather unlikely...
But as I posted earlier, what is a lot more interesting is if factions can change their names during a FL battle as this cannot be done in game but only through support if it is even possible. But to have it changed within the 30 minute battle would be highly suspect since that implies internal tinkering or server hacking.
