For someone like myself and my wife. I believe this will be a great service. We transferred our main toons from a PVE server to a PVP server to raid with some RL friends during the last couple months of WotLK. Both toons are Day 1 toons having well over 500 days played on each toon. Since the release of Cata we have seen a dramatic drop in membership due to the lack of raid progression. I will not get into the reasons for that because they have been dragged through the mud on so many other threads it would be pointless to bring them up here. With the release of Rift we lost the three main officers and the GM. They turned the guild over to my and I would love to be able to transfer the guild, including bank, rep, and rewards to a PVE server. I would love to not loose another guild bank, this one with 7 tabs, to a server change as we already have 2 guilds with 6 tab banks on servers we no longer enjoy playing on.
I think this is a great idea and look forward to the implementation of this on live servers.
