What I have found over the many years playing a Shaman as my main is: 1. The high DPS caster classes have been used to hitting burns, finding great clickies to augment dps, clicking pet AAs, using glyphs, all from the beginning of their character creation in order achieve such high dps, We have only fairly recently (in life of game), started to learn and get used to clicking for dps burns and..it is AWSOME but..you have to be dedicated to going through your clicking sequence. This is something that is not feasible to a casual boxer who's main is not the Shaman. 2. If you are gonna massive DPS mobs...you are gonna get massive AGGRO, this is unavoidable and must be countered by main tank aggro...but since someone is boxing a Shaman, switching back and forth simple doesn't work all that great. 3. Back up healer: Pfft. please, only validity to that is in a raid scenario where their are x2 healers or more..In that case, everyone is a back up healer! I would only agree that a cleric has a slightly more efficient mana pool vs healing power which is offset by a Shaman's DPS, slow, debuff, over all rebuff capabilities. 4. Match MT to Shaman class: IMO an SK is a better tank to match to a Shaman as a box. Long story short, and my opinion..if you aint impressed with a Shaman, you aint doin it right. Heals...check...debuffing...check...buffing check...New and Improved UBER DPS...check. It only took 15yrs but we are at the pinnacle of rounded power now.
