So I bit the bullet, renewed by Innerspace Subscription, upgraded my other four accounts to WoD. I have a Hunter I've solo'd to 100 and I honestly loved it. Felt very refreshing and really fun. Does huge damage and overall just loved the BM Playstyle.

Starting leveling my Protection Paladin and 4x Elemental Shamans. The Paladin is great, lots of different tools and great fun. The shamans... well they are just meh. And their damage on all their abilities just seems REALLY low.

I just fixed up Healing Rain and Earthquake so they all cast on the same spot - and they both are just lackluster as a set of four, let alone each on their own. I realize I'm only 90, and these characters have max professions, and a lot of playtime invested.
My end goal is to PvE, clear heroics eventually, max professions and then play the AH with the combined power of 5 accounts & Garrisons in co-ordination.

Any suggestions/advice? Should I keep going and push through, do Shamans get more powerful and feel less like a wet noodle? What other combinations have anything close to the synergy Shamans used to have with each other?
