You'll all be pleased to know that I have begun updating the first post. Cutting its size a bit and rewording parts.
Issues will look something like this

1. Lack of engagement when there is no need to heal (lack of dps gcds, buffs, debuffs etc)
2. Healing capability is too strong
3. Incoming damage is too weak, infrequent and scripted
4. Healers are too homogenised with no identity.
5. Healers have had core and beloved actions removed with nothing to replace them
6. Healers acquisition of new skills is slanted too far to the higher levels
7. Healers have no depth, synergy or skill ceiling.
8. Healer glamour is too feminine and too cloth focused
9. The healing role does not feel valued as part of the game
