Heroic Rancor... I need your advice

You can get amazing numbers with Teebo (L), QGJ, Rex, Royal Guard, and Geonosian Soldier. Give all but GS Potency, Teebo and QGJ and Rex should also get Speed mods, and give GS a crit chance mods. RG's role is to put speed down on the Rancor. After that, he's pretty worthless, but that Speed Down is very important (so you could change him up with Fives, but mine is strong enough). Teebo, QGJ, and Rex are all about the turn meter reduction, so try to mainly use QGJ and Rex's basics only (and Teebo's if stealthed). GS gains TM when he crits, and has a 1 cooldown special that calls an assist. If Teebo is stealthed, GS's special has a 3/4 shot at a potential TM reduction.
