The suggestion to expand on SCH Protraction effect sounds like a great idea for WHM. It allows the WHM to use more big and pure heals while granting a higher max HP pool to help the players survive burst hits better. Probably the main concern this might have is it could make DRKs a lot more sturdy with their TBN shields scaling from 25% of their max HP. Although that is another talking point since the DRK tanks probably need some reworks to their mechs anyways.
A few more damage abilities would be nice. It would require consolidating some spells together. Cure 1 with Cure 2 would be a simple one. Medica with Cure 3 maybe if they altered Cure 3 to be more better with casuals? I discussed with another savage healer a while ago and it came down to either changing the range to be 10 yalm on targeting with a 20 yalm radius or maybe cut the mana cost in half if the Medica 2 / 3 HoT is present on you. As for the person I was discussing with, they actually went the full mile with some suggestions too. This looks like a thread they made and it has the elemental ideas I remember us talking about. The suggestions sound like it is asking for a lot of buttons, but we need to remember that one spell slot can cram multiple upgraded spell versions kind of like what they did with a lot of the Dawntrail spell upgrades.
