Well I just finished with my first trip in the Kara instance. I was the main tank (oh i switched back to prot) and we killed Attumen on our first try (no disarm either). This was my guild's first run and none of them had tried it yet either so we were all learning together. It was a bit sketchy at first (we wiped on the first pull, mostly cause it was a bad pull and there was no leadership) but we pulled it together, they let me lead them through and mostly call the shots as we went from group to group.
We got to Moroes and we couldn't quite beat him. We wiped the first time cause I forgot you need a second tank to have secondary aggro on him, so the first thing he did was kill my healer. The second time we alllmost had him... he was around 20% when we wiped, but one of our shacklers died because of the garrote (I already used my BoP and I couldnt tell one of the other Paladins to use it) about halfway and we had trouble adjusting to that. The third time went sour as I dunno what was happening with my healer but I dropped pretty quickly and it fell apart from there. We werent able to do it again as the respawns were being too much of a nuisance and my stuff broke a second time and some people had to go.
So we are probably going to try again next week, hopefully some people will grab better gear and we can spank Moroes.
All in all though, it was pretty fun and I'm looking forward to doing it again.
