Hello,
I suggest that all force users classes get to develop the basic abilities that we have seen in movies, such as force lighting, force choke, force push... Because that will make the game more enjoyable in the combat experience, it would feel like our character is having an epic movie combat. And some KOTOR powers like stasis wouldn't be bad. I know that it may break the group combat so here is my solution: when you are playing with a group you must select a role and depending on the role you select you get some abilities unavaiable. Of course, only characters that have healing powers will remain with them, the ones that don't have them actually should not have the chance to develop them.
Thanks for listening.
