I just realized another stupid facet of this comp. It will regularly (though not always) give 4 droid attacks for each enemy attack that connects with BB8. Check the logic:
BB8 is taunting. The enemy attacks him which triggers 100% tm for B2. BB8 counter attacks and calls R2 to assist. They both crit, so each gets 50% tm. Then B2, and R2 each take their turn, which they will take a lot of. BB8 will take turns too, but will basically just keep using that no turn cooldown special every turn until his ultimate is ready.
