Thanks for the work. Actually forgot BC added some quests.

Nice effort, useful to someone.

@Euroman-blackhand

Some Dungeon quests were removed or changed (I did not researh these yet)

Most of these are moved to being inside the dungeon entrances, I think the majority of them stay in the game but the rewards change. Though I am pretty certain some of the old ones are replaced, think DM has the most potentially removed quests linked to it.

@Euroman-blackhand

Battle for Undercity, Alliance (5 Quests): https://warcraft.wiki.gg/wiki/Reborn_From_The_Ashes

Legit thought these stayed in. I have distinct (now probably wrong) memories of this whole chain staying all the way through the phased attack on UC. Goes to show what happens to memory after X amount of years.

Battle for Undercity got removed in Cata due to the fact that the scenario is completely bugged/broken. It still is in Wrath Classic because they didn’t bother to fix it. If you want to read more:

@Aggrend-1483

We knew going into Wrath Classic that this event was fragile, and indeed, the Battle for Undercity breaking was a very common problem in 2008 at original Wrath launch. This event continued to be problematic for the entire history of Wrath of the Lich King until it was removed from the game in patch 4.0.3.

I remember hearing it was a buggy mess in WrathC, I was a lucky one who didn’t have to deal with it bugging out but several guildies had that happen.

Being a buggy mess is a solid reason to remove it even it the entire chain is probably one of my favorites.

Thank you for the link!
