Which rift class should I play I like healing and also range dps so im not sure out of cleric and mage...help

I've found the Chloromancer soul very satisfying in dealing dps and healing the group at the same time. You can access this role if you choose to be a mage. You won't do the best dps, but you'll be able to queue for dungeons as a support or healer. I wouldn't recommend trying to queue as healer myself because Chloromancers are very sub par compared to the cleric class healers, but playing as support always makes the groups go well. When talking about leveling though, chloromancers have sustainability, but take longer to kill mobs. I found it better to switch to a more dps oriented role during questing and then just switch back to support when the dungeon queue pops up.
On the flip side, if you want to be the main healer in groups but still want to do a little dps, I'm told the inquisitor soul works well for that. Druids can also do ok and are great for leveling thanks to their pet healers.
