Boosting Classes & Their "Shining" Instances.

[Mosg2]

My fastest time from 1-60 boosting was just over 7 hours /played and that was with a DK.

1-10 Questing
10-20 SFK
20-35 SM (Can do all three instances in less than 10 minutes)
35-45 ZF
45-55 LBRS
55-60 Ramparts

Edit: The disease damage plus Death Strike is amazing.

I prefer a Bear tank, swipe is 360 and you can use it on the move. Repair cost are typically lower.
