If you really need more than a standard keyboard worth of keys to handle so many abilities, and macros on top of that, doesn't that suggest the game genre as a whole has some serious problems? I'll never understand why MMO players like just pressing buttons for hours on end... Requiring 15+ abilities to do what is easily accomplished with a single skill in traditional rpgs doesn't add depth, it adds busywork. Which makes more sense, a mage that has to cast several self-buffing spells, a few enemy-weakening spells, just so he can cast an offensive spell, or a mage that casts a single fireball for the same effect?
More relevant, I'm actually fine with spending the extra $30-$50 usually required to get a keyboard with laptop-ish keys and a backlight, and this keyboard really is not significantly different from razer's other gaming keyboards. As for the mmo functions, there really isn't anything not already doable with any high-end keyboard, but the price premium is a measly $20 over the $80 lycosa, and its cheaper than their black widow keyboard already. So if you play mmo's and are already planning on a pricey keyboard, why not?
