1 start for making NATE card so rear I have been collecting 500.000 memento coins for a month to get one hero to level 90. and was 5000 short today before and upgrade. and after an update it cost 200.000 + 400.000 now to get to level 90. so now it cost an extra 100.000 to get a level 90. I do not think it is fair. now I will be grinding another week to get those instead upgrading other heroes. And they lie that it cost the same in memento coins to upgrade heroes.
