well, Shadowfang now requires lvl 11 to enter.
SM is still good until 40.
with RAF i did:
Scholo 2-3 times and turned in quests to get to 45. might have to run it another, but hit 45.
Go to ZF and do the quests
do strat until you hit 51. then turn in the quests the quests should get you to 55 or near it. Keep running strat until you hit 55.
At 55, do BRD and just go for the quests. then do to UBRS/LBRS and run each side once. all 3 quests get you from 59 to half a bubble until 60 with raf.
