This idea just got into my mind.
1st, Guild Hall is long overtime in being a part of World of Warcrafts Social systems (Just to make things clear Blizzard would be Scaling down the Utilty by 20 since we saw that in WOD, Garrisons had 10 times more Unility then they needed).
But listen, how about making it so that each guild can choose between spots around Azeroth where to put there Guild Hall/Guild Town?
Think about how cool that could be, Guild could be known for being part of having there guild Settled in an Azerothian Town/city or Just beeing a simple Guild Hall out in the wilderness far away from town/Citys.
Examples: "Method" of Sun Rock Retreat, "Limit" of Andorhal or "ScrubBusters" of Stormwind.
What do you think?
