That MCH dps who jumps into savage is equally able to ruin a pull as a badly as a healer can. So they repeatedly fail mechanics causing the healers to have to raise constantly, losing MP and losing party dps. Or the MCH repeatedly wipes the group due to punishing one shot mechanics (like failing to pick up orbs or hitting their spike on E5s, for example), or the MCH has no clue about their rotation and can barely produce the DPS to beat enrage, which is particularly tight at minimum ilevel.

Dumbing down healer rotations isn’t a solution to the problem. It’s about practice and knowing your job.
