I know other games that make adjustments during the season to balance the game out. And I am fine with that. The only problem here is that we don't exactly know how the GE works, so it's more difficult to properly adjust your strategy.
I think that is an advantage for people like you who is trying to figure out what's going on, because most people just play along. Anyway, if the changes are as small as Marin says, it's not a big deal in the short term.
