What's wrong with arty?

Draschel: Artillery came into the game, I believe 0.6.2.7.  This initial tech tree went to SU-8, GW Panther. People were allowed to pre-order, and shortly thereafter play M6AE1 mutant heavies, @ 0.6.2.1. I was mistaken about the other 2 though, Lowe and KV5 hit 0.6.4.00.But then again, M4E24 and A32 were allowed for purchase and play, just as Mutant 6 was 0.6.2.1So naturally, while not alot of time actually elapsed between the game being played 2010 and artillery's very early release and eventual progression - the game wasn't out there INITIALLY, with SPGs.
