We have quite a lot of epic content right now. With every update we get even more.. (up 17 epic GH?). This change could extend game vitality, give us reason to play 'old' epics. Give us reason to enjoy every gained ED lv. We could feel progress.
Multi TRing to geth fresh XP is natural.. Everything have their end. U cant eat 1 shocolate bar for eyars :P
For those who have more then 2-3 characters it will be harder. Thats true. But why it should be easier??? Whats the reason to aquire everything without a cost??
