I don't have much trouble. I find firing spots where enemies will go past. There are loads on Kamino.
If that doesn't work, I'd recommend charging with sniper rifle. It may sound suicidal. That's because 9 times out of 10, it is. But I normally take around 3-5 with me.
I'm BagelNinjaFail. I'm on PC for SWBF2. If you see me, don't kill me, I'm allergic to death.
