Noting how 4* items only gave 3% to the enhance bar of my 4* phantom bow that was kindly provided by the halloween event, and how little the enhance bar moved for my 5* Freya when I threw 4* heros as her fodder material, I was somewhat upset by the abysmal rate of improvement I was seeing.
So then I thought, why not introduce fodder units to make this horribly slow process easier?
Many other games have a type of counterpart to this suggestion, like exp slimes, enhancement ores, etc., so it isn't like this suggestion is anything revolutionary. Would the developers, maybe at a future date, be willing to consider this suggestion about creating specialized fodder units/ equipment enhancement material?
