So I've recently been playing with a friend who lives in Canada, and he plays on the US realms. I, myself, play on the EU realms.
We've accepted that we can't play the game together because our servers are separated via our regions. Which is something I've never questioned until a few weeks ago, when we discovered we could meet up in-game on the Public Test Realms. The realm choice there includes both EU and US realms. Not only that, but we could actually add each other on Battle.Tag on there!
Why do we not have the choice of playing on other regional servers, if it works on the Public Test Realm? I used to think it was a technical issue, but evidently it isn't the case. Not only that, but other modern MMO's give you the freedom to choose which region you play in (Like Guild Wars 2, The Elder Scrolls Online, etc). Is it because that kind of technology didn't exist when WoW was launched, and Blizzard has never felt the need to implement it? Are there legal issues with it? But if so, then how come other MMO's can get away it?
TL;R; If I, an EU player, can meet up with and have a US playing friend on B.tag on the Public Test Realms, why isn't that an option on Live WoW?
I'd love somebody to answer me, because I'm genuinely puzzled as to why this isn't a feature.
