propose
I'd like to propose a few ideas:
1) Character favorites.
2) Tower-climbing events, lazy and automatically completed after completion, using only energy.
3) Improvements (updates) to old mission rewards, making them easier for new players.
4) Improvements (updates) to special missions.
and making them easier for new players.
5) Returning past events, but making them permanent.
6) Unlocking some things without requiring energy. (The gain would be in reviving.)
7) More arenas, 2*, 3*, 4*, and 5*, separated like 2*.
My goal is for new players to stay and not stop playing because of difficulty or monotony
