I think the best you can do right now is to mood up attack on lee and use earth, 8 gates, iruka and either onoki for the bonus dmg on lee or Mu for his chase cc. Your 4 starred lee is currently your only true carry so you should use him, with some buffs he hits insanely hard and can single handedly win fights for you.

The simulator is not more than 5 days old and there are different themes you can choose from, the one used in the screenshot above is Kurama's theme, there are also 2 tails and 6 tails currently available. I talked to wabbelbomber and he said that he might make the same version in English so that's good for yall.

Props to S12-RockytheDog, S12-Wabbelbomber & S4-MysteryZeus for doing what Oasis should've done a long time ago.

Lee works only in an earth oriented formation solely because he requires that "meat wall" in front of him to keep him safe and the constant shields and earth element steroid plus the 40 chakra from his mystery are all essential parts and without them lee just doesn't function to his full potential. When you run lee you're not looking for ways to increase his sustainability, you're looking for ways to make him dish out as much dmg as possible because that's the only thing he's good at.
