The game allow us to max special skill easily (by giving 5x multiplier) when a hero reach maximum level at the last ascension. However, what about the heroes we don’t want to spend rare materials into?
My proposal is to allow the heroes to keep on feeding with normal succes percentage when they hit maximum level but not at the last ascencion. That will allow us to have the chance to level up the special skill of 3/60 4*, 2/60 5*, or 3/70 5* without ascending them with rare materials albeit without boosted succed rate as in fully maxed + ascended heroes.
