How do I change my avatar?

look up to the left, yep right there

that is all there is for now, you have to wait for the custom ones to be allowed again, and that is on the very soon list.

I see they have priorities in place

and that sucks that we have to wait to get that

I would be surprised it that happens. In fact I could have sworn that they said it wasn't.

It's a shared forum platform across all of PW's games. Some of those games have avatars generated via ingame content so the other games are stuck with just basic ones.

A search of the forums for avatars should see lots of discussion on the topic. (Yes, that's a hint.)
