Tank healing is to high

[Absimiliard]

The truly confusing thing here is how many people are actually surprised. Even as far back as ARR there was an expectation that healers would spend most of their time DPSing. The amount of time they're able to spend doing that has only increased over the years. This has happened in part because of the player-base always looking for means of maximizing their kill times, up to and including sometimes replacing a healer with a pure DPS. SE just leaned into it. Tanks being able to sustain themselves without need of a healer is simply another step in that direction. The green DPS can now concentrate on fulfilling their role to the best of their ability, occasionally rescuing a red DPS along the way.

But uh... for those that for some reason just absolutely want to have to heal a tank; run with DRKs. Their near-total lack of sustain will force you to heal them often.
