Ranking on Kill-Wipe ratio's.
Flame Leviathan - Seriously easy. The wipes are from people who jump into random vehicles the first try and just have fun, without reading the *huge* tactics posted everywhere - we did it the "safe" way, but wiping once to try out was probably faster.
50.8% of all attempts are kills.
Assembly of the Iron - Surprise! This fight is actually very easy on 25. The long enrage timer allows many mistakes, tanks are easy to heal, DPS just need to run from the Death Runes.
21.9% kill chance.
Hodir - He's a one trick boss - the only thing to watch for is his Frozen Blows, just rotate tanks to Shield Wall / Last Stand / Icebound Fortitude; 3 Paladins with Aura mastery = 260 FrR on every blow. People seem to have no trouble there,
20.9% kill.
Razorscale - Fireballs and RNG are evil in this fight, but otherwise it's just a test of how much damage you can do in limited time; get her down to 50% in two ground phases and you're good.
16.3%
Freya - The only thing we had trouble with is the 3 elementals that needs to die at the same time. Survive all 6 add phases and you'll enter free loot phase.
15.8%
Ignis the Furnace Master - Used to be hard, is nerfed badly. Just control the adds and heal - at 22k hp/sec healed on the average, it's at least 50% more than most fights.
12.2%
Kologarn - Balancing dps and healers is tricky here; if you keep all 3 gripped alive long enough but didn't damage the arm enough to release them, you get 3 deads. Otherwise a pretty easy fight.
11.8%
XT-002 Deconstructor - His enrage timer wiped us many times on the first day, but since you have +1 minute to 7 total nowadays, it should be easier. On the
wipe duration histogram, you can see a huge spike of wipes on the 6th minute or 360s.
10.3%.
Auriaya - Crazy cat lady is a touch girl to pull, many many wipes (
over 2k of them) before the first minute passed.
8.7%
General Vezax - Never done him before, but 230 kills on 2618 wipes is a nice
8.1% ratio.
Thorim - Sigh. We're on our 30th try or something, but we get into P3 reliably now, just need more pewpew. Arena part is pretty hard if you have too many casters and healers tends to rip once in a while and get oneshotted by Champions.
6.8%
Mimiron - Not looking forward to this one, the 10 man version was hell already.
5.2%
Yogg-Saron - Can't comment on tactics, but 142 kills vs 5990 wipes is bad

Stats are from all 25 man logs gathered on
World of Logs before 29-4 11:00 GMT.
Notable changes from 25 to 10:
Mimiron needs to be nerfed. At 4.3% kill chance, he is the hardest boss in Ulduar 10.
Thorim is free loot instead of a challenge.
Assembly of Iron is pretty tough to heal with 2-3 healers; tanks still need to spread all over the place, no margin for errors.
