So one of the things that depresses me in WoW today is the fact that on most servers, anything even remotely close to a server community is non-existent. Now we can argue for 40 pages on WHY this is, but I want to know, if you were in charge, how would you try and rebuild server communities?
1. Remove current versions of LFD/LFR/RBGs. Implement new systems that are essentially the same, but only group people from your realm
2. Realm merges. If #1 happens, mergers HAVE to happen to ensure that queues will actually pop.
3. More world bosses. Give people more reasons to group up.
4. More Wintergrasp-like zones. Maybe even add in an old-AV style BG that is easy to enter and leave.
