WotLK: Naxxramas and tuning
About Naxxramas changes, our Lead Designer talked about this a bit in the past, a fight like Thaddius will be pretty much the same where a fight like the Four Horsemen will need a fair amount of changes.
The Four Horsemen encounter wont be nerfed, Think of it like this, if a 40 person fight requires numerous people to be continuously rotating around and sharing debuffs and whatnot, when we remove 15 people from the raid group, we can't require the same number of people to rotate, so it has to be updated to fit accordingly. How exactly it will be changed is unknown, but I'm sure we'll find out eventually.
Bug: Black Bow of the Betrayer still not fixed
This bow still breaks scatter shot. This problem has been in place ever since the bow was in place, and has gone ignored.
This issue was briefly fixed but appears to be re-occurring, a new fix will be in a future patch.
Bug: Eye of the Storm Battleground ending early
We are aware of the issues with Eye of the Storm Battleground on some battle groups, it is being investigated.
Bug: Fozruk loot glitch to be fixed in a future patch
We are aware of these issues (Fozruk cant be looted) with Fozfuk and they will be fixed in an upcoming patch.
