Boosting without RAF viable?

[Sam DeathWalker]

Seige enginerrs in the northmost part of the plaguelands as you go into the next zone (forget if its east or west its near the chappel where the dk qeust ends at)

Black temple top in training area

IF those mobs are to high I think next lower level mobs is pirates in tinnis cove or whatever its called, not srue on that though.

Instance boosting is still quicker than questing even without RAF but it is soooo boring. I'm boosting a team of paladins and it's taken about 17-18 hours to get them to lvl 37 (quested them to lvl 10), each SM Cath run at lvl 25 got them about half a level, now gets them about 24%. But you can do 5 clears of that in under half an hour = 24-25 mins per lvl.
