It would be nice to have more mechanics that target healers only. Just like how tank busters are meant for the 1st and 2nd person in enmity list which are usually the tanks.

Few mechanics come to mind:
- Healer cage in Alexander 7 (Savage)
- Healer portal in Alexander 12 (Savage)

I think there are few more but you get the idea

We have some mechanics that target the furthest player which is usually the physical ranged job to take care of. But there are hardly any mechanics that mainly target healers.
