I went as high as 12k once this tour. Somehow, in spite of the assertion of guys like you that people fly high(20+k) in the MA, I've managed a fairly entertaining kill rate of almost 10 per hour, almost all of this at 8k and below. I'll grant that the late night crowd tends to fly higher... 15k ish. The real truth is that less than 1% of the fights occur over 15k, with probably 90% plus below 8k or less. 
i'm not saying they all do.......
i generally get on around 9'ish eastern. i look for the low furballs. the last time i was in the lw. i cruised at 3k alt......saw a higher con(much higher) turned away to grab. came back at 12k or so. the cons were only a little higher, so i tried to fihgt em. i got popped. came back around 18k, and found them STILL higher than me. a LOT higher.
rather than come in here and squeak about it, i just logged and went back to mw, where i can find fun fights below 10k.
i don't fault anyone for it.....you wanna fly that hi, then by all means feel free............
