Sure about that?
I don't have the time to build the stats like you do, but I know what I see. I don't get to play on the GREEBO map as much as I would like. I admit it is the only map I spend any time in a GV.
The last time it was up and I was on it there were two ..... well Ill call them battles

On one front and nothing going on on the other. The two "battles" were a half dozen guys defending against a horde of 20-25.... buffs and fighters, no goons. The other battle was my squad. I think we had 6-10 guys on and we took 3 buffs a goon and the rest fighters to another base a couple of sectors from the horde. After capturing that base without a defense we upped again for the next base over grabbing up through the dar. Again, no defense and we captured that one.
Last mission, after a number of guys had logged, we went to help the horde figuring we might get some "action" at least, but The horde was down in the weeds looking to vulch and the only planes over 10k were the few pickers looking to pad their scores. As our fighters moved in they ran away.
After that I moved to tank town where even after 11pm eastern there were 20-30 tanks fighting it out on the NE side. don't know how many were down on the SW side as I never got that far.
No I don't have the numbers, but if half the players are in tanks on the GREEBO map, at least they are concentrated in a smaller area. The other half are spread out and so make it look even worst if your looking for air combat.
I don't make this stuff up. It is what it is...... unfortunately. Maybe I should make some youtube videos of how hard it is to find fights these days? Big green darbars with no red in sight. Bases flashing with no dar up meaning it could be anything from a porker in a panzer to a whole squad doing another NOE, or a high alt buff that will bail as soon as I catch him.
No, if I make any videos they will be positive ones. There are problems, and I hope they get addressed soon either in the release of AH3, or tweaks to the maps (put large maps on the shelf and adjust win percentage to help keep the small maps up longer) to hold us over until then.
