You guys should reconsider using Z and X for default controls

[Mors]

Defaults matter.
It doesn't matter how customizable your program/game/etc is, if the defaults are a hassle to some then they'll quite simply not use it. Take GiMP for example: it is an extremely powerful photo manipulation tool but the default settings turn people off enough to use Photoshop, which has quite a hefty pricetag whereas GiMP is 100% free.
I have all my stuff set to use A and X for controls, which feels a lot better on the hand then having the fingers right next to each other.

I didn't say that they didn't, and the problem isn't Z and X being bad. They are pretty much considered the standard at this point. The problem is them not working on all keyboards which can be said for pretty much all other layouts, including A and X, and the only real solution is allowing people to change their controls. There's really no point of changing something people are familiar with if it's not going to really fix anything.
