If you are looking for just ranged DPS you want to run a 61 Inquisitor spec ( http://forums.riftgame.com/game-disc...tor-guide.html )

This is a bit intensive on the rotation since it has a 60 second cooldown worked into the middle of the rotation but it is the best a cleric will get at ranged.

If you want to eliminate the tank you could try multiple druid's with tank pets but I doubt that would be successful.
