How would you make each healer dps rotation unique?

A simple diet coke BLM rotation for WHM for example. You can make aero work similarly to Thunder, AoE version that doesnt stack, stance change button, stone 1 & water 1 for single target, stone 2 and water 2 for AoE. Make stone and water spells be the same button based on stance to reduce bloat. change free cure to proc off of Water spells and reward a lily. holy can be your foul equivalent. At the same time move lillies down into ARR level range and build their healing kit around it so a WHM's MP economy is mostly used for DPS while lillies give plethora MP-free heals. Yes its still a 1 button rotation but having stuff to micromanage makes it better to play.

As for AST honestly just copying dancer with their RNG feather procs and card themed standard and technical staps sounds most fitting rn but i also toyed with the idea of making a card themed Ninjutsu from NIN.

SCH will be a little difficult since the current iteration of Arcanist doesnt fit SCH gameplay at all. Maybe make it a dot themed class with Bio Miasma etc. Kinda like bard, with tacticts skills that proc off of dots.
