Special Character Purchase @150 credits

Anthn3y

Why is it for almost the last 7 or more purchases for special characters at 150 credits points in this game, I only receive level 2 or level 3 players, why isn't it possible to straight out purchase a level 4 or five player. This game is totally ripping me off, this is like my 3rd time wasting money I'm so done with this process if you advertise it make it available please!

They do advertise is correctly. It says a increased chance at a 3 or 4* of said hero.
I will say that it need to be a better chance for the price they ask. But this is why I don't wast my units on crystals.
