Finally we choose to take on this challenge and we prevailed.
When we first started out in heroic we knew tactics wise that Ursoc was one of the easier bosses. But seeing as we just had the dps to kill the first boss within the berserk timer we choose not to go for him. Instead we went for the dragons and Elerethe Renferal and spend time to kill them. After nearly a month of raiding we finally took on Ursoc as we felt ready.
In some of the earlier attemps we saw that we both had the healing and the dps to kill him. We just had to sort out the tanking problem as the boss got moved a bit to early and to far, so the space wasn't filled out good enough. And the tanking on that fight was a bit more complex than other bosses. So after that had been sorted it was just pure trial and error and after enough attemps we finally managed to kill Ursoc.
It's a simple fight, but hectic in the end which is nice. But Ursoc please try and stay away from corruption. This is the second time we had to put you down.
