So, the current event has a rune drop in the Easy and Hard dungeons. At lvl 48, that means Improved runes for me. My question - does the hard dungeon offer theoretically better runes, since it's "harder"? Or are the potential rune drops the same in either one? I only ask because I have 3* both & plan on doing some quick looting to get a stash of runes for some of my lesser used heroes.
