Nah Moarsi won't do it. He doesn't pay for his 6*
In all honesty if Step 1 wasn't there i would consider it an amazing deal (you would basically get only 5* and above) but Step 1 ruins everything.
Look at it this way:
You pay 180 $ and maybe you will get 3 Rainbows if you are really lucky but you could also participate in three different Step Up Gachas (60$ each) where you can choose your 6*.
