Guild Wars 2

I got a few questions about world transfers. All of my friends are Europeans mostly from the UK and one from Bulgaria. I noticed some of the EU servers have [DE] and [FR] i’m assuming those mean DE for German and FR for french, is that correct? Also if i want to play with friends from UK what server should i transfer to? i’m not at all worried about my ping it was crap even on the NA servers, i just want to play with friends.

if its pve or spvp any server will do, if you want to WvW with them however you need to be on same server.

Thank you. they’re brand new to the game so i will just be helping them level for a long while.
