Quoting your earlier reply:
Also my earlier reply might fit the context on what I'm about to say, but we are paying customers after all. Indeed, people can stop paying and move on, but new batch of unsatisfied customers will come and complain about the same issue. It was done so during ShB, during EW and now approaching DT.
If we stop paying and move to other games, nothing will truly change, will it?
Then again, the game doesn't revolve around just playing healer role, there's plenty to do in the game that isn't just battle content.
