Id rather have Specific Companion Flashpoints where its you and your entire crew with unique rewards, maybe companion specific gear? instead of having "solo mode" for existing flashpoints
i would go for this. maybe make it a way to earn end game gear for your companions instead of grinding out more BH coms after you finish out your toon's set. i could totally see my smuggler going to a terminal on Port Nowhere to check for daily "smuggling jobs" where things might go wrong and she and her crew end up having to fight their way out of a hutt's palace. though it would be hard to make fights as epic as they can be in FPs/Ops due to the fact that companions aren't as smart as human players. still, would be awesome to see them all interact with each other.
