I've just received my new Realforce 55g keyboard, and some of the keys on the left side of the keyboard (mainly A, S, D, G and F) seem much more pronounced than some of the other keys on the board. They almost feel like they are much heavier than 55g. I think it's more to do with some lube, maybe, on the sliders? They feel a lot smoother and much more thocky than the other switches. Should I be concerned that the board feels uneven because of this or will the lube eventually wear off? Thanks.
