FFXIV community is obsessed with healers doing DPS because all fights are predictable where there is a lot of down time where heals simply are not needed. SE says they want healers to be more heal focused but then we are given dungeons where healers don't need to heal half the time. All the fights are scripted so once you learn the fight ,you know whats coming next with the most randomness being boss is either gonna go with a "X" style attack or a "+" style attack.
