That's how wow elf ears, Draenei horns and stuff work and there's no end to complaints about the clipping.

Trust me, they add hats and people will complain about the clipping.

Me, I'm more irritated with the birth date thing at character creation having two 2/7 dates. 2/7 is both 7th and 8ths of that Umbral moon and it bothers me more than ear clipping
