Its even harder now to level up hero
The evolution is interesting but it is hard to evolve once reach 2 stars because the cards needed are at later stages and two stars heroes are really not strong enough to take on those stages. The only way to get the cards needed is to level the none five star cards but that wastes a lot of resources.Also when hero evolves you need to start from level 1 again, and some of the cards needed to evolve can only be obtained from call to arms. It just takes so much time to just get the card to five star so we can finally start level it up from level 1.
