There were some hidden changes.
The Gunship fight will no longer reset if no one is outside.
And C'Thun had his one-shot-ability removed.
Did both fights a couple of minutes ago. (On my way to Kalecgos, perhaps he changed too).
Sorry for my bad english, I'm german. And if some of you speak german too, you can check
out my big guide to all raid changes in 5.1.

No changes to Kalecgos, still impossible.

So, after i've killed all the changed Bosses on the PTR.
Here are the changes in more detail:
Viscidus:
You only need 20 frost attacks to freeze him.
After that you need 30 physical attacks in 30sec to kill him.
Twin Emperors:
The healing got reduced. You only need 16k dps to kill the bosses before the enrage timer kicks in.
C'Thun:
The one-shot ability got removed. You can kill the tentacles inside the brain and then go for
the boss again.
Al'ar:
He is not immune to fire damage anymore.
Reliquary of Souls:
Essence of Desire casts Spirit Shock every 10sec, the debuff only lasts 4sec.
Gunship Battle:
If all members are using the cannons and no one is outside, the battle doesn't reset anymore.
That's it for now.
Viscidus, Twin Emperors, C'Thun, Al'ar and Reliquary of Souls should be easier to kill now. The developers applied a hotfix during the night. So, if you haven't gone to C'Thun yet today, you should! |

He's now easier to freeze and shatter. RoS won't cast Spirit Shock as often as before. What about Razorgore? I'd say you need to practice the most effective path and use his ability to sleep dragonkins. Razorgore can also take quite a beating, but at some point you'll need to clear adds off yourself and himself (careful of not blowing him up). |

The changes the developers made were mostly on some TBC and Vanilla bosses. They didn't modify anything from Naxxramas (although you have 3 pets there). But just to make it clear, the intent they had at the time when making these changes wasn't to make all the raid content from WoW/TBC/Wrath soloable. Just as an example, although it's TBC content, Rage Winterchill will still give you a run for your money if you are not careful avoiding Death & Decay (since it's % HP based) :-) |
|
Regarding Kalecgos, at this point we don't know if the developers have any plans to change him or any other bosses, but we'll ask them and share with you any news if that's the case :-) Just a small update this, which should hopefully come as good news... A last minute fix was made to patch 5.2.0 that should allow players to solo the Kalecgos encounter in The Sunwell :-) |
|
I cannot yet say if it will be this week or not, because there is still some preparation that needs to be done before the patch is ready for launch, but it should be quite soon now :-) |
