I understand the revenge wave concept and agree that it is fair but calling in four of the same titan on one revenge wave is kind of going overboard......
here's a glitch, get an item (no ghostly medallions, boss trophies etc.) go to inventory pickup the item and then go to options and drop it in the gray box. you just ate/absorbed the item and its stats:)
 "Epic War 3"){kind=icon}
 "Sonny"){kind=icon}
