I come and go from Sim League baseball, I occasionally check in to see if there's been improvements, but there never is.
Every team in open leagues look the same. These teams aren't full of fan favorites, only broken players that everyone uses. There's no attempt to fix these players that perform well above expectations, or to adjust their salaries upward for the amount of times they are used. Because of this, every league is the same. This means no excitement, why would I want to come back? 2019 Ketel Marte again? Yay!
Maybe there's a risk to lose the 50-100 most hardcore players if you adjust how broken the game is. It seems the majority of players are unimaginative and really like the broken players, so I understand there's a fine line to walk with any update. But trust me, you'll never get a flood of new blood into WIS if they can only use 2019 Ketel Marte or lose. There's no fun in that.
