Math Strikes Again. 

U ain't never  go to the store and be like man this shirt too expensive for nothing. To give u 5 pulls for $50 is insane. if I spend that on dokkon or db legends that's like 50 pulls. And to have no banners is wild. And the fuse system is diabolical I need 16 blue characters at max rank and four purple characters at max rank to get Pelops is impossible. but a new player gets him free.

Once you develop a account to the point of hitting unm and nm clan boss every day, and being able to farm stage 20+ dungeons, fusions become pretty trivial as long as you play smart with your resources. 

No idea what you mean about banners, is this referring to champions with group auras? You only have one team aura active at a time so it doesn't matter if every champion has one.

I do agree that the pricing is insane. All modern games, especially phone games are completely insane with what people will spend, its why these companies will continue with the absurd prices because fools will pay, and pay a lot. The good news is you can play raid completely free, and be very successful and complete all the content in the game as well as complete all the fusions. Many have, and free 2 play raid video series are popular on YouTube.
