Me and my friends are out of the game since cata, but want to come back to WoW.
Problem we are facing is that we have all played on different realms before, but are gonna play together on one realm @ pre-WoD launch
Now the question is, since the introduction of Battle net and such as where you can quest and group together cross realm,
What are the key elements of the game that have to be played on one realm, to be played together? Or is most of the game x-realm already?
Ps, dont know if this was the right place to post it, but it seemed worthy.
