Wow Lusche, you continue to amaze me with the data you have at your disposal.
Coupla thoughts - first, a question, really: What vehicle(s) introduced Q2 in 2011 that caused a significant increase in G2G kills and a drop in A2A kills? Something happened back then that really braced the ground game. Any idea what it was?
Second, the decrease in vehicle K/h since AH3: I'm wondering if the new graphic requirements hit the ground gamers harder - that is, as a group is it possible they had more low-end systems that could not handle the new hardware requirements, and had a larger percentage of players who either chose or were forced by circumstance to leave the game? Its curious to me, because I think the new terrain improved the looks of the ground game quite a bit.
cheers
