Enter into rifts.. all gear stays behind in Telara.... must find/craft all new gear ... PA's stay put.... All gear obtained stays in the according world until you return. With earth air fire water and death... each with it's own progression path without mudflation the game would have so much room to grow. Hardcore raiders could continue to be as hardcore as they like on Telara while the casuals could get their 1-50 fix so to speak in each world. Later they could start adding raid and pvp content. Death could be a PvP world.
