Today I come to propose an addition to the team since I talk about it with other people and it does not seem bad to them.
My idea is to put some kind of "bands" of team that start being easy and then they are going to complicate until being the last of level 450 or 500 each personage and that there are for example 50 bands in total (not that they are infinite like the present ones ) and that each victory achieved gives him an extra level to the exp boost and team gold; the maximum would be 50 more levels and therefore + 100% exp and + 100% coins. It would help people play more challenging and at the same time help teams not get stuck simply because they have already improved everything with donuts or no more donuts to donate.
This idea is used several more games of this style and keep people of more than level 400 trying to overcome these missions.
Give your opinion and if you like the idea to support and share it
