Which 10 man bosses have you downed with only 5 chars?

[Malekyth]

80 content : Noth, Patchwerk, Anub'rhekan.
70 content : Magtherion, Hydross, High King Maular, Gruul. Karazhan completed. Zul'Aman completed.
60 content : MC completed. AQ20 completed. Zul'Gurub completed.

I should try Sartharion. I think I'm well enough geared for it so I'll give it a go. Any tactics/tips?

You did Mags and Gruul with *only 5 toons, or 5 toons as part of a larger raid? I wouldn't have thought they'd be possible even at 80. I'll definitely give them a try if you were able to burn through them with only 5 total.

Just my pally and 4 shamans, nobody else. HKM is the annoying one. Magtheridon and Gruul are just tank 'n spank basically.

Maxion did the first 2 in VoA (http://www.dual-boxing.com/showthread.php?t=30022).
