This is a lying money pit. They advertise heroes with powerful stats, wait until everyone spends money to get the "limited time" hero, then turn around and nerf the hero to make them weak in the name of "balance". It's not true one bit. They do it so you'll spend more on the new heroes. Then rinse and repeat. This is not honest business. They are deceptive. Stay away from this game unless you feel like giving away your money to be semi-competitive. And even then, it will never be enough.
