I feel your pain on the trinket issue. I recently took the plunge and ditched my Essence of Gossamer. It was a wrench to see my unbuffed health dip below 30k again. I made up for it by making myself a little mini-cooldown button by macroing together two trinkets and my herbalism heal – this gives me 5k of health (2k of it over 4 seconds) and 5k armour. I hope this will be useful on melee-type bosses. For magic-damage bosses I will swap my stamina trinket back in.

On the boss issue – one thing to consider for Freya is that you will get four emblems (the trash bosses drop easy emblems too). This might help your gearing up. The only hard thing about Freya is the three adds which have to be killed together – if your dps is on the ball, or you have a dps leader who can call out the targets over vent, you’ll be fine.

I found Thorim pretty easy (my job was the tunnel tank then helping tank the boss). The tunnel itself is not much harder than the UP heroic gauntlet before Skadi (although the boss AoE comes faster), and if your dps is awake then the healer mobs can be burst down pretty fast, allowing you to zerg the second mini boss really quickly and clear up the melee mobs later.

Also noticed the “storm cloud on me” on the demon. I don’t think I’ve ever noticed that before, but I don’t have chat bubbles on. Hmm..

And yay for successful casual raiding.

My tip is Thorim, as long as you manage to sort out what adds do what it’s sort of trivial – survival in the arena is fairly easy on ten-man so the gauntlet people can take their time. P2 is a DPS race but it’s pretty lenient as long as you have decent healage/tankage. Freya requires tonnes of coordination, Thorim is just “don’t stand in the fire”.

Good luck on your progress!

And yeah, all girls, all proud.

Freya/Thorim, I’d go for Thorim first probably, I think it has a slightly easier learning curve but they’re very similar difficulty really.

I like those legs but… expertise (ie. threat) is not something I really need. I’m only just over 540 at the moment, so whist the legs’ avoidance is awesome I’m not sure I’d want them because of the defence complications.

I presume you checked the whether using defence yellow gems, defence cloak enchant, plus defence elixir would do the trick?
Gravity´s last blog ..Dodge 3.2

Maximize Frost Resist (I have chest, treads, belt, ring) and with no defensive trinket I can still stay capped at 540. 3 pieces should be mroe than enough for 10 man. My tank gear is not that impressive (Dozenz, US Server garrosh) and when I first killed him I had only one gear that was ilevel 213 or above (Boundless Ambition)

But more imporantly…

Save shield block for frozen blows. Pop Last Stand for first Frozen blows, shield wall for second, Valor Medal of the First war for 3rd, and by 4th Last stand should be back up (glyphed for 2 min last stands).

For the final last stand I use Enraged Regen as well to assist with heals….could also pop it during Valor use as that is the weakest of the cooldowns I use.

Also keep Hodir tanked by a cozy fire. It keeps you from getting frozen in place from the Frost Nova like ability (and keeps healers healing from having to dispel) and you don’t have to wory about the stacked debuff.

We found Freya easier than Thorim, but both are easier than Mimiron, at least when we were learning Ulduar.

As for the pants, I try to avoid Expertise if I can, but since every piece of offset gear is made for DKs/Warriors, I have it in spades anyway.
