I really haven't written much about Ulduar. Let's face it, I really haven't written much at all lately, but that's besides the point. The point is, that I'm coming to you today to give you a HUGE pointer for taking on Deconstructor in Ulduar. He's so easy, that he's essentially the new Loot Pinata for 3.1. Even more so, he's a robot, just like another Loot Pinata we used to know in TBC.
So... this "guide" assumes you've already killed Flame Leviathon (which is really the first Loot Pinata in Ulduar), because you have to have killed him in order to get to the next 3 bosses. I'm also not going to regurgitate what you can find on many other strategy guides out there. Go check out one of those guides for how to deal with the different abilities and what they are.
Come to think of it... this is really less of a "guide" and more of a "really, really big, helpful pointer". I'm guessing that the guildie that came up with it read in on a web site somewhere, I just don't know where that is.
All of the guides that I've run across tell you to tank Deconstructor on the stairs, at the top of the stairs, or at the bottom of the stairs. This is absolutely incorrect. Here's the secret: Tank it between two of the scrap piles on the side. Either side will do.
"But Leiandra? Won't the bots come out and heal Deconstructor immediately?" Nope. That's the beauty of this positioning. And maybe I'll be the one to bring this to Blizzard's attention so they fix it (lol.. like they're seriously reading my blog), but when Deconstructor is tanked close to the scrap piles on a side, neither one of those 2 piles will spawn adds.
Done it on 10-man. I've done it on 25-man. Both ways, you only have to deal with 2 piles of adds instead of 4. It makes the encounter much more trivial. PLUS... those slow bots have to walk all the way over to the other side before they can do anything. Trust me. You're gonna thank me for it.
