Encounter Design needs to be overhauled at a fundamental level

[Boa-Noah]

What they need to do is remove all dps spells from healers entirely and make the damage come from casting heals or off globals.

That's a very bad idea, back when the game first came out Healers had basically no DPS and were very hard to level up or play at all without being in group content, they had to change things to give healers DPS and even then had to further incentive people to play a Healer class with mounts and achievements. Same for Tanks though less so, they still had to implement draws so more people would play Tanks including those nifty mounts again.

Personally I don't want to go back to those days.
