Well, the point of having something like this would be to make it challenging and fun right? Well they could always introduce a second version of everything with a sync. For people who want to have fun, not mindlessly grind. While still having a normal version where you keep your item level. This way everyone could be happy. I am sure there would be things wrong with this but i mean everything has flaws and someone is always going to have a temper tantrum when it isn't how they want it.
