How can we get more in depth character customization?

[MageBlack]

I love how tanks can and are expected to put out a certain amount of dps. Roles need not be so narrowly defined. DPS is how the boss dies EVER. if there is no dps, as in damage, the boss sits at 100% HP until enrage. therefore dps is the job of EVERYONE, but DPS are expected to do more than others.

I think thats only needed in the current EX content. Everything else is poopsock-able.
