For us old-timers here, a great feature would be to have the option of resetting our Ascension materials on older heros so that they could be used on newer heros. Not sure if there’s a thread about this yet.
One big frustration amongst the older folks in our alliance is that we keep getting better and more useful heros, but have, ages ago, used rare materials on heros that are just not as strong anymore. I would propose that we can reset all Ascension materials on any hero. As a consequence all food and iron are lost and the hero from whom the items are being taken reverts back to 1/1. You have to take ALL the materials back, not just the ones you want. Plus, maybe a 100 or 150 gem cost. This seems reasonable, and would seriously please A LOT of people. It would also be super easy to implement.
