In the end, I'm still short medals to buy all 5 pets, and I'll need nearly all of them to get the 75 pets from my current 61. Got an Azure whelpling for 800g, and a the Dalaran horde-only kitty for 1000g. Boy that sucks. The rest of the whelplings I hope to farm and get from eggs.
Arenawise, I'be been running with a guildie mage, and learning on what can and not be done, like e.g. that mages can't polymorph druids, and that a dps duo is in general better burning the opponnent dps than killing the healer while the opponent dps is loose. Boy are healers hard these days. 1300 rating, going smoothly up.
Raidwise, a lot of improvement. Got myself a decent Soulfire MH and another Ulduar ring, Naxx HC wand, bringing my average gear to 210, and my spellpower to 1803.
All bosses seen and learned up to Freya, it'll be a walk in the park from now on.
Thorim is our current stall point, and no solution for the arena mobs yet.

I had a misstep on Hodir, where I simply kept getting too much damage, while ppl talked about runes and the need to run away, but I couldn't see any fucking runes, only some falling rain sometimes and then a snowy platform. After some searching, it turns out that Blizzard decided, for 3.1, to add a nice "checkbox" on video settings "Projected Textures", and tooltip it with "disabling this will greatly improve performance". Fuck it, I unchecked it... and guess what.. that shit setting disables rune viewing on Hodir, so I was most time on top of runes, getting screwed :(
It's a pity that we don't have enough geared ppl for 25-Ulduar, our latest tries there was a wipe, after one successful clear of the first 3 bosses. Our leader decided to set class officers, so I've now got the job of making a health checkup and tip list for our fellow and future lockies, so we can help'em improve their dps. It's not possible to see ppl dps'ing below the tank level, it simply won't work.
