Tank healing is to high

[Aluja89]

You know that this isn't "tank versus healers versus dps" right ?

This is a *team* effort, if a single member makes others irrelevant it isn't fair nor fun. Especially if it is easy to do so.
Soloing bosses is fun, when it's a challenge. Not when it's just because other players are optionals.

That logic goes both ways though, why should the rest suffer because the healer can't keep up? They also feel irrelevant when the healer dies, now there's less scrutiny towards healers which should be a positive.
