Anyone complaining that they can't win a fight with maxed stats aren't using their abilities right. I ended the game with like 10 weeks to spare having unlocked every achievement, and my run was far from optimal
The only Idle game the scales faster and not slower. Doesn't have a way to make that work so it is kind of boring. From level 75 on I just went through mass levels, leveled up for a while and then went through levels again. I upgraded maybe 10 times between 75 and beating the game at 302
