I returned the Nostromo I recently bought. It doesn’t quite work out for me as a WoW player. The reason is pretty simple: It doesn’t have enough buttons (needs more than a standard keyboard) and just ends up being a funky interface with no apparent gain (as opposed to the Naga Epic which is funky, but has a pretty good upside with its ridiculous amount of buttons.

Anyway, I suspect one of those gaming keyboards might be better suited for WoW since you might be chatting or accessing certain panels which require the more standard keys. (e.g hit ‘j’ for the guild pane)
