It's alright hahaha. :)
Speaking of losing sensitivity, my rarely pressed X button lost its. It's a bit funny, you'd expect that to happen to the A button. You know what's stranger?The X button is back to its perfect state! @_@
When you said replace, you mean repair, right? Or have you got yourself an n3DS?
They fixed the diversity issue from BW/DP by altering their respective regional dex. But XY is a bit tricky, it doesn't have that issue. That's not to say I'm against of the idea, on the contrary I'd really love to see them changing the menu. :D If possible, they should include those Pokemon that weren't part of the XY Kalos dex, like Totodile, Seedot, Beldum and so on.
