Ewoks have amazing tm manipulation. Han just adds to it, so it's not uncommon for the little furballs to attack 2-3 times per enemy attack. But, han can only taunt once every 5 turns. RG is great for saving your weaker ewoks, like chirpa or elder. Plus, they both help keep RG's health full for continuous auto taunts, and elder revives him easily. My advice, get stormtrooper han maxed, and use him until you are able to get RG playable, probably gear 8, 5 star.
