No, you can't be matched with people from other regions because bonds are available only since 19:00 to 22:30. There's not even one minute during which this time span overalys the same time span of another zone.

So when is bonds time for you in uk is not bonds time in hk, la or ny zone so they can't join even if was actually possible for them to be really matched with you.

Those two people are in uk region, the point is in which server.

Personally speaking i matched one 163k from server 543 last time...

P.S. since you are in s20 you are for sure in a merged server so you can go to character interface and select to show the number of the server. If you select it it tells you also the number of the enemies servers when doing xserver features too.

EDIT: a guy posted uk power ranks in a new tread. There's a 224k guy with a weird name, it's him who you matched. The other one was tiffany. Server 163 both.
