Are those the only toons you have? You might think of rolling some other "alts" to give yourself some more options. You could roll 4x of anything and boost them with the pally. Or, you could just move the holy pally to the priest account, and have a "healer" account and swap out accordingly. My plan is to have a healer acct, tank acct, and 3 dps accounts. I plan on having some failover though, for a 4x dps 1 healer setup for PvP.
