I have been running some of the old raids and have come to the conclusion that some of these old raids had a lot more work put into them than the new ones.
My favorite is Karazhan, from the moment you walk into kara you are hit with an eerie feeling and even the smallest detail reinforces this feeling.
You start with the ghostly stables, home of Attumen the Huntsman who is rumored to drop a mount. (Never for me apparently)
You then encounter Moroes and his ghostly guests who are dining on a wonderful meal of what looks like 200-year-old ham. Back when Kara was a progression raid Moroes used to be somewhat of a raid breaker because of the CC needed to successfully beat the encounter.
Next up on the list is Maiden of Virtue who resembles Freya. I sucked on the floor tiles many times during the maiden fight because of healer priorities. (And by the way for you tanks out there, She goes commando)
Next is my personal favorite The Opera Event, which is one of four different encounters that changed weekly. I used to get the biggest laughs out of the little red riding hood encounter, there was just something about all these people running around in circles to avoid the Big Bad Wolf. The opera event takes place in the large theater of Kara with hundreds of guests watching.
Once you beat the opera event you unlocked the side door to kara and started at the Broken Stairs, You had the option of giving Nightbane a try if you so desired but he had to be summoned with a special item and a lot of groups skipped him for this reason.
Hidden behind a bookcase further on is Terestian Illhoof who was a warlocks dream boss. Seed of Corruption, Seed of Corruption, Seed of Corruption, and after that… Seed of Corruption. Terestian Illhoof was an optional boss and most groups would skip him if a warlock was not in the group.
This second part of Kara had some complicated trash pulls and a lot of them. You eventually worked your way up to Shade of Aran who I think wiped more new raiders than any other boss. When someone new to Kara asked about the fight the typical response was “You will be dead anyways so just watch and learn” The arcane explosion killed new people every time. On the positive side once you downed Shade of Aran you opened a teleport from the entrance back up to his room, So wipe recovery wa much quicker.
The next boss was Netherspite. At the time Netherspite was a major pain and most groups skipped him altogether. Corla, Herald of Twilight is much like Netherspite with a few major differences. In the Netherspite encounter the beams all have a good effect and a bad effect some people had to rotate in and out of the beams according to role or class to make the bad effects less of an impact.
The Chess event was next and it is one of the easier fights. If you told someone you wiped on the Chess event You would probably be laughed off of the server. The only way to describe the Chess event is to say that you take part in a game of chess as either Horde or Alliance versus the other. And you physically took over the chess Pieces.
Finally you climbed to the top of Kara and Encountered Prince Malchezaar. This encounter was hard for melee classes to get the hang of due to the number of times they would have to run away during an enfeeble. If they ran too slow one time they were dead.
Kara took a good 2 nights normally when you were on farm, due to the sheer size of the place. I would love to see Kara rebuilt into a cataclysm raid.
In closing if you have the chance take a trip to kara if you never have, But be advised Kara had an Attunment and even though the attunment is gone you still need to have the key to get into the instance so have someone with the key come and unlock it for you.
