So i understand that to bring up the objective wheel you hold up on the D-Pad. How do you rotate around to choose what you want? Is the the left stick or right stick? I think it would be the right stick. Does anyone know for sure?

Nope but one or the other. Mappable controls anyway.

That's a pretty easy one. No dev is stupid enough to put the method of selecting objectives directly on top of the thumb that you need to hold down to keep the menu up. It's going to be right stick. Plus I think they described this in one of the gameplay walkthroughs. They didn't say which stick it was though :sadvaultboy: Just assume it's right since it's more ergonomic.
