Precisely. This is my second time trying it. First time through I played DS, so I'd have an easier time with Drain Life and Force Lightning. I made mistakes with that character. First of all, I loaded up on Strength. Not smart. My force powers were too easily shrugged off, and I couldn't use any Wisdom increasing items (their all LS restricted).

This time I'm going with LS.
I'm a 6/14 Scoundrel/Consular. Being a Scoundrel is important, because of the damage bonus you can get from Sneak Attack if an enemy is unable to attack.
My favorite move is to first use Force Choke/Death, then to Flurry them while they cannot respond. It usually takes enemies out pretty quick.
