EU and US instances/party groups.

Hello,

Can you limit instances/groups/partys to EU/US regions as-well? It's getting really frustrating, happening since the 0f patch.

I'm on EU and i sometimes join party/group who's host is in US so my ping magically jumps up to 400. And even after i leave the PT i sometimes stay at the US instance with 400ping so i have to reset map few times to get back to my normal 50ping.
