Ah yes, the "fall back" argument for people who are usually wrong. Please, also throw out the words ad nauseum and ad hominem and you can sound completely idiotic.
Until I ask for RACIAL TRAITS to be universal, my request is nothing more than using a Gnome to accomplish the same means as a human, worgen, or night elf.

Tecnically, Trolls can already be every class but one. So, in the interest of balance, all races should get to be all classes save for one. But, people would still likely place horde since the racials set them apart. As of now, every race can be a Warrior, so I guess by your definition, all warriors are homogenized.
