I have a 67 bard with 150 aa's (def max cept for OOW), die in Vxed usually about once every 2 -3 hours. This is without any modifications made to succor me & mend when I get whacked, deaths also could be attributed to lag because I run a torrent whore on my network as well. Kills with 3.0 drum average about 4-5 minutes but time could be reduced by altering my song arrangement and not belting out the chorus of marr, however, my death per hour rate would increase (unless I figure out a way to remove that damn statue in the room to provide more kite area).
I figure I average about 1 aa per 70 min (death times inc), in FH average is about 1aa per 80-85 min (not bad if you are looting too, about 800-1000p per aa and adds only 5-10 seconds per kill), HOH aa exp has been 1 aa per 75-80 min, repop time in there kills the additional exp unless you occupy more than 1 room. Not sure of aa's with a group because my hermit bard does not like other people.
Sorry for the incoherant babble, at work and that has pretty much sucked all the life out of me.
