Yeah, same old netmarble. Putting lots of restrictions and invisible paywalls in making the characters amazing and viable to force player to either quit or spend their money. It's quite a shame for amazing IP's such as kof and marvel to fall into the companies hand and make the player to spend more by luring them with nostalgia while hoping to ease down the difficulty but instead make it harder so that only those who pays can enjoy the game and those who pay to pay more. What a vicious cycle!
