I highly doubt multiple claims systems really gets confusing. We had Raid and Normal versions in XI for years. It was a pretty simple concept the grasp, the only issue was the shared item pool could make things hectic when it started filling and evacuating too fast. Of course, Dynamis is getting revamped...

Either way, this is something Yoshi-P really wanted us to discuss, and I'm surprised it hasn't come up sooner. I hadn't even thought about it until I saw this thread.

I hope everyone takes the time to read my long post as it does address a lot of how the problem evolved.
