Keep it semi simple. The Battlefront idea was simple and it more or less overlapped regular game experience but forced you to do or play in a certain way.
Big problem is if it's anything like battlefront - newer players are going to get stuck unable to complete a lot of them, I'd say it should be lvl 85 and up, at least by then you probably have something like depth in your team (potentially)
I like it. It'll probably be more of a head ache for most people and too easy for established players.
TBH I think I'd rather see more options in current combat. Just a touch of tactics, maybe the battlefield scenes all have something you can interact with (like the rancor door control) IDK. Shoot X and a barrier pop up and a toon can use it for cover. I really don't know, but I wouldn't mind expanding on the battle experience before overlaying exterior things on how you do the battles.
