Rancor as a usable character. And reworked boba fett (soj). Or add a GL boba.
Lets be honest boba fett scion of jango is currently pretty useless and not worth the grind..
But if he would get an omicron ability to summon his pet rancor from the show allot will change.. Like make it work where if he is alone on a team or with fennec and (beskar) mando that his rancor will be a summoned unit and gets to sit on it, and that the rancor needs to be defeated 1st before boba can be killed.
Or if boba is alone on a team in gac or tw that the rancor will have an ability like gl's that needs to charge up, and is gonna be able to eat any unit and make them unable to get revived. Might be a bit to op ofc but not if for example the enemie needs to have lost all of its protection or be at a certain hp% .
Or they can add dark shaak ti (from the force unleashed) who gets a rancor pet.. that works similar, we need another character who can be alone like wampa.
