The reason we healers DPS

[Reinha]

Oh tanks will still try to pull wall to wall, it'll just stress the healers out to no end leading to some massive burnout.

Healers are the only role that claims to be stressed when performing its primary task using all of its skills. I for one would welcome end game dungeons that are harder hitting than leveling dungeons, and tanks pulling wall to wall to challenge me further.

They’ll never bump it up to the level of ultimate content and even that is about 70% downtime.

70% of downtime in the hardest content is utterly ridiculous. Imagine the boss went away for 70% of the encounter and tanks and dps were just sitting there not able to perform their role. It sounds like healing potencies could be cut in half and people would still be able to meet the healing requirements.
