I just wrote quite a lot about how shamans are fun to play, have a lot of versatility in the buffs they bring and can pretty much fill any role that currently needs filling in your raid. Then I hit the wrong button and it was all gone, so this is the short version:
Shamans can quite easily change between raid healing & tank healing with just a change of glyphs and the spells you use.
They can choose from a pool of buffs to benefit the raid as much as possible and bring the unique buff Heroism/Bloodlust which is a great boost in most encounters.
Shamans are all about fast choices, especially when raidhealing. Do i cast a Chain Heal or is a Riptide / Lesser Healing Wave combo more efficient; do i sacrifice a few ticks of my hot to supercharge another heal or let it tick?
I simply love healing with my shaman, because it's fast-paced and it's all about interaction between different healing spells.
