So, you can supposedly play with your friends, but no, not really, I invited my son's character to a group with me. But no, he did not phase with me so we could play together. This had worked up until today. No friends on other realms questing together , just people taking everything for their high pop servers while diluting the community and annoying the hell out of everyone.
If they can't be of any use but causing annoyance can we please just opt out of them or better yet scrap them altogether, maybe put them someplace with new coke and other failed endeavors.
