As a tank, and a very old one at that, I believe that the fact that everyone is doing what he's supposed to do is already a good thing : a Tank that tank properly without stressing too much the healer, a DPS that dps properly without taking aggro and the healer who keeps everyone alive all along the run. The fact that healer SHOULD dps during a run is actually a new thing to me since FF14 ARR. I've never seen something like this in FF11, WOW or any other MMos in my life and I can tell I had my share of tanking. However, over time, I came to believe that if a healer feels comfortable healing AND dpsing at the same time, fine by me. But never i will blame a healer that wants to heal only because he believes that its sole duty. Healer should dps ? its just because everyone just wants to finish a run fast like eating some fast food without enjoying your role. That's the way the players are now.
