With RAF, I tried 5x BM Hunters.
Got them to 60th.

Also did Druids, Priests and Shammies.
Almost did Warlocks, but decided on taking the Shammies to 80 instead.

Added a Pally to the Shammy team.

Hunters are a fun class.
I personally enjoyed Boomkins and Disc Priests more, but the Hunters were quite fun.

My current (70) solo Hunter has respec'd back to BM from Marksman.
I've put her into a mixed group, which will be doing BG's.

Her /Click Castsequence macro looks like this:
I personally "spam" at two clicks a second, and have the comma's adjusted for this.
