My issue was that I'm an ex competitive pc gamer, who plays a lot of FPS and actually used his gkeys and LOVES backlighting. They pointed me in the right direction as far as what to get, as well as showed me there are a fairly large number of pro gamers using mechanical... Lots of people told me originally that mechanicals are too loud, or terrible for gaming, that they are specifically for typing. Boy, were they wrong. It may actually be the opposite, although they were right about them being amazing for typing.
