I’m not even sure that the problem is about the amount of new heroes we get but it’s more about the time you have to spend on a single hero. Considering the droprate and the absurdly short amount of time between two lvl cap updates, you need to know what you want.
Now balancing IS a thing that the game NEEDS. But will Perblue listen to that ? I really doubt it.
Let me take an example : I used to run a team with Vanellope (Dash disk ? Well the disk that allows her to deal more Damages to slowed enemies) and Finnick. The synergy was great and many opponents were underestimating that duo.
But even with a little refresh, who will play Vanellope when you have a D&B who can destroy a team with a single attack ?
And that’s why you want to invest on new heroes, and you might want to spend money for that.
I’m not giving a single penny anymore to Perblue until they fix it. I won’t blame people who does it, though.
But this game is all about money and it won’t change.
