I would have to say that when going through the game Force Wave was my bread and butter of any difficult battle. If Force Wave didn’t work for whatever reason and I kept having to do a battle over and over I would just lay a little area of landmines. After the landmines are set just get the baddies attention somehow (grenades) and have them chase you into the trap. I know it is a cheap way to beat an enemy, but I justify it by telling myself that might be a way I would do it in a paper and pencil RPG 
Everyone seems to like loading up on Jedi, but I found that replacing one with Carth - remade into a saber-dual-wielder - worked just fine too. He hits damned hard, and if you slap a mind-immunity item on him (belt, implant), so much the better. My preferred team for sweeping the last area became Carth and Canderous.
WHOA!!!
That was a surprise.
I don’t think too highly of Bioware’s writing (gimme Black Isle any day) but it’s one hell of a twist, hey!
