Sarth 3D is doable with 5. You might lose some guys, but the whole thing only takes 10 to 15 minutes. Pretty easy way to get some achievements and a nice mount.

Ony was np. She went down pretty quick. I am amazed at how fast we can take down the old 10 mans now lol. It's a lot of fun.

If you can bring 7,8,9 or 10 guys do it for the achievement. I can get 10 accounts loaded on this comp and it runs ok. I had 7 or 8 with me yesterday to burn down Sarth quicker.

Or, grab another boxer and go for it. It's a nice change from dancing around the heroics and trying to get the new bosses down.
