Please create something like an EP storage system as another functionality of Shared Bank where players can simply store their unused or available EP to their Bank like ED.
EP is seriously useful but at the same time, limited. You can only use it to buy stuff through Ariel.
Or you know what?
Just make the Epic Points also convertible backwards.
Players mostly need ED, not Epic points anyway.
Man, just bring back the only ED Shop in the item mall, the EP Shop is too restrictive.
