Honestly, I've lost confidence in the Battle Team and the ones directing the battle team. They've lost connection with the player base and just winging it, fueled by success and arrogance. It's not just about Healers either but the whole game design is slipping.
After they had to save the game from an arrogant producer, they made a battle system that work with job that complimented each other. Jobs had a skill level from easy to hard. Jobs had different designs of playstyle. Now Tank Roles and Healer Roles are basically carbon copies. Jobs are being dumbed down for greater mass appeal. Non of the key issues from expansion after expansion are being address because the Devs think everything is fine; the players are just playing the game wrong.
I may not be a healer but I do know this group has point blank told the Devs exactly what they hate and exactly how to fix it; it's an insult that they just flat out ignore the player base.
