It's more about learning it.
Controllers in FFXIV are surprisingly well done.
Even if you're using keyboard and mouse you've still got to learn all the controls to perform well, it's just learning a different type of control.
I was once in aurum vale and we had a dps get kicked for afking.
Had a Ninja replacement show up in his smallclothes, I had assumed he was glamored to the emperor's new set gear... He wasn't.
He had on accessories and his daggers, that was it.
And, according to him, he didn't have any gear for the class on him, and wasn't near a town to have picked it up...
