I vote for doing nothing till we get more info about the rework for Epics
What more do you need to know? We'll slowly work through older Epics, bringing their Stats in line with the new formula as seen on the new HCTitan. This shall be done via Inventing, combining 2 or more original items with other items in the game. These could be from GvG, Arena, PvP Ladder, etc.
