WHM:
1) Nothing to do but spam Glare all day long. Healing is reactive, the whole role is designed about being reactive. It's horrible, we need something proactive to do other than spamming one button. There are many ways that reactive healing could be more engaging, like simply having heals way weaker so that it's actually a struggle to keep the tank alive, but ultimately as both tank and healer gear up the need for healing will always go down. That's when we need something proactive to do, no more one button 'dps rotations'.
2) People telling me WHM is fine because it has the best numbers out of all healers. Couldn't care less about numbers, those can be hotfixed in a small patch. What WHM, and actually all healers, is lacking is fun gameplay.
3) Healing sets that look good on male characters. Can we have some?
