We started on Ulduar25 yesterday with my guild. We tried to do some raiding on patchday, which of course was sheer impossible.
Our first plan yesterday was to do the new VoA boss first, so we could write it on the progressionchart after which everyone was free to PuG it in the future, but seeing that Alliance lost WG in a very short and bloody battle, we decided to head directly for Ulduar.
We were all amazed by the coolness of the Flame Leviathan fight, which is a big step up in originality compared to the other WotLK raids. We proceeded to one shot him. After that we went on to Ignis, where we even wiped on the trash. We decided to give Razorscale a try first. When I say, a try, I of course mean 2,5 sweet hours full of wiping and trying to learn a fight. We didn't even get him down in the end.
So what do I think of it? Well, I have to say, I loved it! I'm not gonna say my guild is really hardcore, and think of everything as EZ-mode, and OS+3 only a minor challenge, neither did we one shot everything the first time we set foot in Naxx25. But we did get every boss in Naxx down on the first evening we tried them, and mostly we had multiple first kills in one evening. I'm really glad to see the difficulty has changed at least so much in Ulduar, that there are actually real challenges and there's actually the possibility of wiping multiple nights on one boss :)
Tell me your experiences with the new and improved WotLK raiding :D
