Why no cross-data-center pvp?

[Claustrum]

There's no PVP specific restriction on cross-region travel. No one can travel cross region for any purpose.

I'm talking about data centers, sorry. I'm being very bad about describing the problem for me. I use the NA data centers, and during the hours I play, it's extremely hard to find pvp matches (or ques for anything else, but I can log in to another data center for pve). So I would like the ability to log in to another data center to make it so my pvp que timer is less than 180 minutes.
