I'm relatively new to FFXIV, and I couldn't help but wonder why there is so much cross-over between roles? With the mmo holy trinity, (Tanks, Healers, DPS,) the differences between the three should be magnified as much as possible!

If any tank is putting out enough DPS that is comparable to DPS classes, then obviously DPS classes need buffing, or that tank class needs nerfing. It seems that there is a fundamental game design flaw that needs to be addressed more so, and that flaw is the DPS overlap.

To fix it, tanks need to mitigate more damage, deal less damage, dungeon mobs need to deal more AA damage, damage should be normalized so there isn't a magic vs physical tank, then poof you have a stronger tanking role. If healers have time to be DPSing, then there isn't enough raid-wide damage to keep them busy. DPS are like the only role in this game that have a good role!!!
