Yet another shameful money grab. You want people to pay $40.00 USD for a single champ, only to have them do it again for the next one? Then you are going to make it so that the ONLY way to get them is to pay for them?
It is really a shame what you've done with this game. On its face, it is a pretty decent offering of the genre. It reminds me of a game that does more and does it better in Summoner's War (the original). This game is NOT an RPG, the story is about as thin as a layer of mica, and it has become extremely predatory. This is a pay to win Gacha game, nothing more.
I've invested a lot of my time and effort into this game and I have a pretty decent account. It used to be able to compete in arena Gold. Now, I am lucky if I maintain in Silver II and that is if I get lucky. I am constantly getting match ups against teams that are over double my power score. What? Now there are new Meta champs every few months that make it even more difficult to compete. I don't mind that paying players get access to better things, more of them, and at a quicker pace. At least give me a chance if I invest my time. I feel with each passing quarter, that is becoming more and more of a fleeting notion.
If you want to lose more and more of your player base, keep it up.
