Play with friends
i thought they let you have a week of free transfer when you started. to settled down to a home server
Server transfers are still free, just have a week of ‘cooldown’. But I think the problem is that the targetted server is full. That sucks, but I’m not sure what your idea is exactly. Either wait for it to get space, anet increases server sizes (again, I hope not), or find a different server all you guys can go to.
The only real thing you can’t do with friends is WvW and map completion (maybe story too). IMO, dungeons (with the exception of some story quests) are the only things you really would benefit from playing with friends. But I understand where you’re coming from
