Force Leap is way cooler than Heroic Leap. I have a sentinel now and it's kind of similar to fury warrior maybe from TBC but with 10 additional keybind. You have focus spenders and generators and your rotation is built around longer cooldowns 9-15 seconds instead of every 3-6 seconds.
The best thing about playing Jedi Knight is that you don't have to contend with any frost mages or sub rogues.
