ahh I forgot about the whole milk more food cost per level system that is built in. If you want extreme detail on how thats worked out check out this https://forum.smallgiantgames.com/t/required-experience-and-food-calculator-for-any-hero/9832/24
- An idea for a new system that would be less annoying would be to have the cost per feeder be a flat cost per tier instead of increasing at each level and each tier, and have every level ending in a 0 require much more experience to compensate.
while they are at it, it would be great if they reworked the tiers and number of levels per tier to match what they did with their other game Puzzle Combat. Instead of 1/50, 2/60, 3/70, 4/80 they have 1/20, 2/40, 3/60, 4/80, 5/100 and this layout applies to all star ratings of heroes (all heroes have the same number of levels at the same level, higher star heroes just have additional tiers).
OK I am aware that is extremely unlikely to change due to the issue of what to do with partially leveled heroes, but what they can do is make unfarmable 3* ascension materials display as 4* and the current 4* asc mats display as 5* just like Puzzle Combat. This would be easy to do as they would not have to move the assigned value given to those asc mats since they are in a bunch of reward tables, simply adjust the display graphic so that those items now show as 4 and 5 star.
