Team for Commander Luke

If you want, you can do (most of) it by pumping Luke Farmboy to g12 and his strength compensates for any weakness in others being below the recommended gear level.

For example, I had Stormtrooper Han and R2-D2 at about gear 7. But with Lule Farmboy 12, it didn't matter.

NOTE however, SPOILERS FOR THE GAME, Obi-Wan has to fight by himself at one point so he needs to also be pumped.
