I got drafted into a 10-man, so I got a chance to see what all the new bosses are like.
Lord Marrowgar seems...off to me, somehow. The coldfire and bone spikes are fine, but I just don't like the whirlwind phase. Which is kind of odd, because I really liked Leotheras, which featured the same switching between whirlwind and normal.
Perhaps it's because Marrowgar is so large. Leotheras was much smaller, so when he whirlwinded, it felt like you could avoid him if you were clever. For Marrowgar, I just head for the hills. As well, because of his size, everyone goes out of range for healing.
That's actually one of my pet peeves about certain raid fights. I dislike fights where people go in and out of range seemingly at random.
Lady Deathwhisper is an okay fight, but nothing really special, at least on 10-man. I think this will be more interesting in 25-mans, as the extra mobs will add more complexity to the fight. Actually, looking at WoWWiki, Mind Control alone will make life interesting.
Icecrown Gunship Battle
The Gunship Battle is simply awesome! Airships, cannons, repelling boarding parties, boarding the opposing ship in turn, jet packs, Muradin Bronzebeard, High Overlord Saurfang! This fight has so many different elements, and yet they all combine beautifully to form an insanely fun fight.
I particularly like the way Saurfang is used as a phase-enrage timer, with his self-stacking buff. It gives the players a chance to engage him in combat, makes it imperative to board the enemy ship, kill the targets, and get out quickly, but also retains Saurfang's essential badass-ness.
Simply a great, great fight.
(Not sure if Deathbringer's identity is considered a spoiler, but I will err on the side of caution. Note that the link to fight reveals his identity.)
Deathbringer is an interesting fight. It's a good fight, with interesting and challenging mechanics.
However, I wonder if Deathbringer will be disproportionately harder for Gentry guilds than it will be for Aristocracy and Royalty guilds.
Basically, Deathbringer stacks Blood Points whenever he deals damage. When he reaches 100 Blood Points, he puts Mark of the Champion on a random raid member, and they take damage whenever Deathbringer deals damage. So the Marks act as a soft enrage for the fight.
The thing is that some of the abilities which grant Deathbringer Blood Points are avoidable. So Gentry guilds will be hit with a double penalty. First, Gentry DPS is lower than Royalty/Aristocracy DPS, so more Marks will be handed out. Second, Gentry are more likely to make small mistakes when it comes to the avoidable Blood Points. People won't be far enough apart for Blood Boil, or they'll get hit by Blood Beasts. So not only will the Gentry get more Marks because their fight will be longer, they will accumulate those Marks at a faster rate.
I think that combination, that double penalty, might make the fight harder than expected for lower level guilds. If any of the available fights gets nerfed in Icecrown, I expect this one to be the first. And the vast majority of Aristocracy and Royalty guilds won't understand why.
So far, the first few bosses are pretty good. I loved Gunship Battle and Deathbringer, and enjoyed Lady Deathwhisper. Only Marrowgar didn't seem that fun to me.
