Ok, if you're actually using that team line up as is, that's part of it. Yeah, use the "total power high-low" for the my-set one, but don't actually USE that set to do the levels, you just do it so that your helper squad is strong to aid OTHERS. Use the other tabs to make ones for yourself to use. Main thing is balance the power out on your teams. Your top team in your current setup isn't gonna have issues, but the rest likely are, so you want to balance it out so that while every team my get a bit beaten up, they still are capable of killing the enemies and at the very least making it to the boss (some likely WILL die on the boss, but with others behind them, its not the end of the world)
