This is redic... so you're telling me that:
1. I bought 1.0
2. I bought Realm Reborn Pre-Order CE b/c they shafted non Legacy 1.0 members and I wanted Early Access/pre-order items
and now I have to buy CE upgrade?!!!!!!!

This is total mistreatment of 1.0 members that already bought this game... twice!
