Here's my little report about our Molten Core and Onyxia progression:
Molten Core is absolutely well scripted, with the exception of a few small bugs that Chero is already aware of and i guess they'll get fixed very soon.
Molten Core being well scripted though, doesn't make it hard for an experienced group of players (and really, who isn't experienced when it comes to Molten Core ...) so yeah, Molten Core was quite a walk in the park considering the factors that a few people already brought up in this thread (the post 1.10 gear from 5-man dungeons, the 1.12 talent trees, the players' experience etc).
Chero and the Kronos Team, in order to make it a real challange even for the most experienced people, would have had to customize the Boss encounters so heavily that you wouldn't be able to call them blizzlike anymore after such changes.
Some people had asked them to do that for Molten Core before the server was launched, i think you can still find these threads on the forums here, but Chero decided to keep it the way they are and so it is no suprise that Molten Core gets cleared as soon as the first Guild/Group reaches Majordomo and Ragnaros.
Is this a bad thing for the server though? I don't really think so, because it is difficult to even make Molten Core a challenge. There is people complaining that Molten Core is too easy, that's because Molten Core is kept blizzlike in terms of damage and hp values.
If Chero had modified these values to counter our status of Gear and Talents, other people would complain that the bosses are not blizzlike, you know .... so no matter how you do it, people will tell it's wrong.
Even over at our competition (other server not to be named) Molten Core got cleared after 2-3 weeks, just like here on Kronos. And that, even though they tried pretty hard to counter that, by changing all items to their pre 1.4 values and telling their community that they would tune all encounters to their pre-nerf state (which is BullSHit btw).
So, i can only say that Molten Core is scripted very well, almost flawless. (With the excpetion of Ragnaros killing half the raid before the encounter even started... the GMs saw that incident and it denied us the first try kill)
BUT, something you all can excitedly be looking forward to is Onyxia!
Onyxia is very well scripted already, on our first kill there was just a small visual bug in P2 where Onyxia was not always facing the right direction, which made it harder to see where the possible deep breath would be hitting down, but Chero was telling me during our progression that he was already aware of it and that the fix for that was done already, but just not applied to the live server yet.
When she comes back down after P2 she is a bitch to get back under control and that's what i loved about her!
It was a real pleasure to progress on her and she was actually able to wipe us a couple of times!
(We gotta keep in mind though that we've fought her with less than 30 ppl, we don't know how it will look like with a full 40 man raid)
so far so good, all that's left to say is, don't judge the difficulty of Molten Core by the progression of the Guild that gets the Server First Kill. In our case we've prepared more for it than normal guilds would do, we had many players that leveld like crazy to get there so quick and the people we had in the raid were executing very well.
There will surely be guilds that will wipe here and there if they don't watch out carefully.
As for Molten Core i can absolutely accept that it wasn't all too much of a challenge, but on the other hand, i hope that Chero will learn a little from it and tune up the future raid content a little bit. At least for AQ and Naxxramas. Cause nobody would want to see a guild that clears those raids a week or two after they come out.
and as far as BWL is conerned, us from <Synced> will not demand from Chero to open BWL anytime soon!
We didn't clear MC and Onyxia so fast because we want BWL out as fast as possible.
I think the wording they are using in the conent progression is just unsuitable. It gave some of you the impression that they would open BWL like a couple of weeks after the first kill of Ragnaros.
I don't think that was the intention behind it, but yeah, the wording was not the best.
I don't expect BWL to come out anytime earlier than 2-3 Months and i think that would be a time they should aim for. I think by that time, the community should be ready for it.
Thanks for hearing me out! Hope it gave you the small impression you were looking for.
