Guild Wars 2

I know that guesting hasn’t been implemented yet, so perhaps this question can’t be answered at this time. I’ve searched this forum, but nothing definitive popped up.

I sure hope the answer is yes.

It is yes. You can join a guild on another server than your homeworld or while being in a guild you can still visit other servers. However, when having a different homeworld than the guild you cannot join them in WvW.
