I've already got 5x Priests at 60th.
They are currently Disc, but could go Shadow quite easily.

I went with:
- Anthràx, Blood Elf Priestess
- Ebolà, Blood Elf Warlock
- Malarià, Blood Elf Warlock
- Cholerà, Blood Elf Warlock
- Diphtherià, Blood Elf Warlock

They have formed the guild <Pestilence>.
They will eventually BG, as an off-set of sorts, on my same server.
I'm in the process of transfering gold, via the neutral AH to cover their expenses through slow flyers.

I'll level/gear them Destruction, but respec to Affliction once they're half geared and close to 80th.
