I've got a resto shammy (63) a rogue (80) and a Blood Deathknight (80) all on alliance. My main is on horde, so I want to xfer 2 of these three characters to horde and keep one alliance. I can't make up my mind. I think a troll resto shaman would be good so I think that one is going, as for the other two I just have no idea.
What reasons would you give for me, for or against, faction changing (or keeping them as alliance) any of these 3. I'll get them all to 85, so ignore anything relating to leveling.
