I have no idea how SE can fix this tbh...
I think they either did not see how raids changed the healer role and/or they have been too slow to react.
There was no new healer this expansion so they could balance the current jobs and the healing community is even more divided than ever...
Really can't wait to see if the next expansion finds a solution that would be suitable for most or creates an even bigger rift.
Not sure if that changes anything in my message but I hope it makes you happy at least. Have a great day.
