I don't know if this counts as spoilers as it's very general, but there's your warning.
How does your class typically kill people in story mode?
As a Sniper 90% of my kills come from me pulling out my pistol and shooting people. The coolest kill that I can remember my 38 Sniper doing was shooting a canister or something and blowing some guys apart.
My Sith Juggernaut has much cooler kills IMO. Most of his kills come from either force choking a scrub out or just plain stabbing/slashing them with my lightsaber. The coolest one that I can remember was when he used the force to pull down a huge crate hanging from a crane onto a group of mine workers. It was pretty awesome.
