I haven't bought OoW yet; frankly, it doesn't have that much to offer me.

However, I do have some of the new graphics; I see the breathing and there seems to be "more" rain when it rains that can make it hard to target for mezzing - though I don't have shadows.

I thought there was supposed to be an "advanced" button in the Display tab that would let you go in and turn things on/off.

I don't have this. Is this an OoW-only feature?
