Healer role design change?

[Zeastria]

1) More damage and dmg you cant prep or know in advance:
a) Damage over time, so that healing is req all the time.
b) Boss target random player and use x ability (random dmg).
2) Only healers should have ress!
3) More to dispell.

Healers should be able to use their full toolkit,
and not just spend majority of the time useing ST dps and OFFGCD when dmgs hits..

This will make it so healers have to heal more often.
They have to use their full toolkit -> this prevent healers to just spam their ST and offgcd when dmg hits.
Remove heal-dps check. however healers should still dps during downtime.
