Last week we killed High King Malgar and Gruul killed us. This week we got both of them down. For HKM, I tanked Olm the Summoner along with the Felstalkers that were possessed. This helped control him and led to our victory.
Against Gruul, I just off-healed. I have 1000+healing so I actually helped. Some of my gear dropped, but I won none of it. A trend of late.
