If this game has a competent dev team that understood how to properly tweak numbers then you could have both the league and base game be fine. But the devs don’t know how to balance or design hero’s that aren’t pure cheese. The last hero we got that wasn’t cheese is wrecking ball and he is considered a troll pick below diamond with how many people lack the ability to not feed with him.
CC, burst healing/burst dps are among the main problems that need to be dealt with and after that throwers, Smurf’s, cheaters should be dealt with. But that will never happen.
