There is tons redundant spells for all healer that there is no need for them or you can keep them at 1 button
Why we have spell to enhance healing by 10%?

Just add it to the core healing kit.. there is no need for filler healing spells or make it 1 button instead of 3 doing the same thing

It is not engaging using same spell for 3 button doing 90% similar activation

Instead add more engaging buffing/ debuffing / dps rotation
