Using the same kind of tools
So, yes, one way of handling this is to give every tank a burst AE attack like Thunderclap, a sustained AE attack like Consecrate, and a mass taunt like Ether Saga Online Gold just for good measure. That is the kind of thing we are really reluctant to do though because it just works against the justification for having 4 tanking classes when they all perform the same way including using the same kind of tools.
