The request is about the list which shows all obtainable monsters in the current egg (golden egg, spezial egg, festival egg or rare egg).
I would like to have some indication, e.g. by a checkmark, if a monster is already obtained. So I could see how many monsters from the egg I still miss.
Currently, the list shows the names of the first form, which I often don’t remember (especially for SEs) and then I have to search somehow in the Monsterdex in order to check if I already obtained this monster.
They won’t because people will see and find out that many eggs aren’t worth spending for given they own more of the egg pool than they probably realize. This will lose them $.
