i didn't have a hard time with him at all in fact i only healed myself once... i used all my stims then when he heals himself the first time with one of those jedi i ran around using death field on all of them (you must have missed one or somthing) then i fought him and killed him... he didn't run to try and heal or anything.
also on the unknown planet if you chose to go dark side... then you can make Zalbarr kill Mission.. thats what i did... felt good too.
