5*?
As a basically new player, only playing for a couple weeks getting 4* somehow, dumb luck actually (the first premium was a 4*) I have seen the campaign and some arenas as a way of getting 5* but I do not understand if that is the only way of getting 5* (Minus Events) If so after the Campaign is 100%'d does upgrading turn into a grind and not worth it or quite the opposite? I am honestly lost because the only thing for units I can see is that they can buy items and some special offers and Premium. Can Units buy 5*, or at least a crystal that has them. If anybody knows send feedback I am wondering how.
Also when a hero/villain gets 99 signature ability what happens.
If anybody knows would be nice to hear it, also if any new chances for 5* are coming that too
