Achievements Suggestion
Here's an idea, if a player completes all the achievements for a mech - that mech produces 10 a-coins daily.
I think it would feel more rewarding to complete as many mechs as possible and keep people playing more. The final rewards are either skin or 20 Fortune Keys. This is kinda weak considering that you have to spend 2850 a-coins to upgrade mech and complete all the achievements.
I have a few sitting on 99% because I see no worth in spending 2850 a-coins to get 20 Fortune keys and +2 capacity on the mech.
Please consider this or something similar. I think players deserve better rewards for the struggle to get to 100%.
Thank you.
