I was wondering if you have lots of advanced runes stocked up but not that many medium runes is it better to to upgrade everything to 165 first on 1 character or to try to upgrade existing 165 till you get to advanced level so you can start spending them?
Since its harder to upgrade higher level am i correct in assuming its more efficient upgrading lower levels before going for higher levels with medium runes? Ive been waiting for event here but was wondering which was better since i got well over 100 advanced runes saved up.
