I keep suggesting this repeatedly. Diversifying the jobs within the role makes so much sense to appease the different angles various people want healers to go in and it fits right in with the lore and history of the jobs. IMO the big holdup is that SE are somewhere between being unwilling or unable to put the time and effort into implementing and tuning something like this. Healers have historically been rushed with far too little testing and tuning done for expansions and I’ll be surprised if Endwalker changes that (Sadge allowing).
