Well some of this is clearly bullshit. You won't ever recive exp from the mobs THEY are killing inside. You may quest doing the instance, but you will only recive the 30k exp if you ain't getting kicked.
Rather do a AV and get 150k exp doing premades.
We made one on al'akir with my DK, we was 24 level 76-79 (Most of them where twinks) And we had instant queue and 3 awesome old tbc tanks, and lots of resto druids to help us out. So we went right to Galv and afterwards to drek, without taking down any towers.
