Our heals are the largest mana wise of all the classes, and do the least amount healing. We can dispel a druids hots, but when our teammate is getting hit hard for 7-8k by their dk every 6 seconds, how will i have mana to heal him when I am spending almost 400 mana to dispel 2 hots that cost a fraction of the cost.
Then, lets say the druid goes oom. I am oom too by then. Then guess what? He barkskins and innervates and it's game over.
Lets see who can move faster or stay on a resto shamans that are melee. Everyone.
Every class has a get out free card except shamans. Grats. There's a reason a majority of resto shaman rerolled priest and druid.
