Yeah, once again Pay To Play rears its ugly head. They did a little better this time around with the energy requirements, but honestly, not by much. That was one of my biggest complaints about Injustice Mobile.
It's just too damn much. I understand microtransactions. I understand getting people to pay to have top tier equipment and cards...
But to just be able to play the damn game? It's so frustrating. Especially when you consider how much grinding you have to do to level up to get past certain bosses, or even earn koins just to be able to purchase upgrades or other characters.
Frankly, it's just not good, honest game design. It's still an unabashed, blatant attempt to grab your cash.
