Here's another solution:
Place mines on the battlefield before confronting them. Battle starts, battle won
You just have to have enough mines and sufficient demolitions skill of course. Average Frag/Sonic/whatever mines should suffice.
Other things that can be helpful in this battle are force speed, stimulants, and flurry of course. And one more thing: Re-equip your armor right when the battle starts! It is totally legal in the last few battle, but it isn't possible anymore once you're infight.
I must admit I actually had more problems with the first few fights playing as a consular or a sentinel as you were limited to hand to hand combat only. Optimizing your equipment for maximum hand to hand dmg and defense can be helpful here.
Anyway, I'm playing on the highest difficulty level and always managed to get through somehow. Just be a little inventive and everything should work out fine.
In case you're playing as a Jedi Guardian just forget all I said and hit away.
Hope I could help.
So long,
Sol
