My guild killed Heroic Stone Legion Generals tonight! 9/10 Heroic Castle Nathria!
Actually, it was decided to drop Normal entirely, so we started on Heroic Tuesday. We got through the first 8 bosses fairly smoothly, even with a couple new people on Council and Sludgefist. We even got a few attempts on the Stone Legion, and laid down our strategy.
So tonight we went in focused on them. It took a few pulls, but we killed them after an hour or so. In Heroic at least, it's just a matter of doing all the mechanics, and making sure to clear the various bleeds that you can get.
Then we started doing Sire Denathrius attempts. Phase 1 is very finicky, so it took us quite a while to get that smoothly and start seeing Phase 2. On the last attempt of the night, we had a very clean pull, and ended up pushing him into Phase 3. Three-quarters of the raid was dead at that point, though, and the rest followed shortly.
Still, quite good progress. A couple more weeks of practice, and we should get him down.
