PLD no flash?

You could have both that switch between magical and physical phase so that no tank would be optimal for the whole fight. Or, akin to the missing number in FFVII, a boss that could be locked into a specific type of damage depending how/when you go below a specific threshold, so that could adapt your strategy depending on the tank you have.

They can do a lot of things if they want to. Heck even having to sit out on raid set (like delta) and then being good on the second (alpha) could be an acceptable solution. They fact is, for whatever reason, they don't want to do it. Hence they picked the easy way to make all tanks the same, which in my oppinion is the worst thing they could do for the game.
