The JP community doesnt have a problem with healers or their design. Their solution to if you dont like how healers are or want more dps buttons then go play a dps job. And the answer to if you want more incoming damage go play ultimate. To where your gameplay loop at lower level and casual content up to savage can be solely dependent on other players messing up.

For many people there is the copium of job design changes in 8.0

They want to redesign the content this expansion and do jobs next expansion. However it should have been the other way around, especially considering this is lvl 100 we are talking about.

Basically if you dont like healers in DT either dont play the game or play something else and wait until 8.0
