I had the impression that v4.4 was going to give us one free Epic Battle per Event.
I certainly used one during the Frostmage Event, then again during the Hierophant Event. But the one I had for Invasion seemed to disappear after using the Hierophant Epic Battle (actually Mythic, of course).
Is it perhaps one free Epic Battle per platform (I did the second on Android, for the achievement)? Or did it start out one per Event and has now changed? Or something else?
After going back and rereading the patch notes I can see where it could be confusing.
“When playing an event in 4.4, all players will get to try out an Epic Fight for free the first time.”
I could be wrong, but I interpreted “the first time” as meaning the only time
