Frustrating Smurf!

I use zMaul lead, DN, SA, Zavage, and Palpatine. My strategy is to shock shore with Palpatine, making Kenobi taunt. then just focus every on Kenobi. Use DN force drain ability to increase cooldowns, and keep focusing on Kenobi. Shock shore if he loses his shock while you are doing this, and use SA's lightning to stun Thrawn just to keep him from using his Fracture. As soon as DN can annihilate, hit Thrawn. once Thrawn is gone, the team falls apart fairly easily. The downside to this appoach is that their DN will probably annihilate one of your toons, but after that, you don't have to worry about a threat from any of the opposing team, and you can just mop them up. A lot of the times, you'll kill Kenobi, and maybe even DN while waiting to annihilate Thrawn.
