I would love too, but it would be pretty rare. We play a good amount of apocolypse, so dropping 13,000 - 15,000 isn't that unheard of. The most I have ever used is 8000. I normally have a partner to help run them though. Like I said, my dream is 20,000 but I also have no illusions that I will ever truly be able to paint them all.
Much of the reason I have them all is so I can field every kind of army there is from green horde to speed freak to dredd mob. I love them odels, the play style, and the variety.
Would be nice to have some sort of reliable shooting...
