It needs to be done. It is the only way to allow f2p players a fun game. I personally am not f2p but I feel that if gree wanted to make epics unfusable it should have been done from the start. Now the spending elite will just further themselves from the majority of the player-base. With that being said I do believe that the rates should be nerfed. They made a huge mistake with how easy it was to get a epic with the right combo.
