Guild Wars 2

With all the changes to the servers with Megaservers and Guild Unification, I was wondering:

What does guesting affect now?

I only wonder because I was thinking that if it would allow me to gain access to another copy of Frostgorge that did not support the toxicity that Anet has been supporting I would guest more often.

Some players have found they are on different copies of the map once they have guested. I suppose it depends on each account’s algorithm parameters and the specific map.
