Like the title says, which caster comp below would be the most well-rounded taking into account dungeon leveling as well as max level dungeon grinding/gold farming and wPvP?

1 priest/3 locks/1 mage
OR
1 priest/3 mages/1 lock

The single lock/mage is added to the respective comps for the convenience of summons, wipe recovery, portals and what not.
