I like the calculator. If you guys feel its worth it, you could add an option like "sum of first X steps at Y% discount", so that we could estimate how much cost till 15/20 MU.Though its not very difficult to do with calculator, but it would be nice to have such an option.

loading time for battles was so long...... plus rank brackets were too wide

Triple mission rewards were a desirable update, and much needed too. Next they need to increase the rank up rewards by 3 times to expand the player base.
