So I was working on my Argent Tournament dailies yesterday and saw someone advertising in General for a few of the Icecrown group quests that I needed to finish for Northrend Loremaster. A half hour or so later, this absolutely fantastic boomkin and I (later joined by a warrior) had finished about 7 of the end of the line group quests in Icecrown and I was happily in possession of Northrend Loremaster and a shiny new Deathchill Cloak pattern!
I also gave in to my occasional spastic urges to raid and joined a guild group for Ulduar 25 last night. It start out OK with us quickly downing Flame Leviathan and Ignis, but then quickly became a wipe-fest on Razorscale and Ignis. It did help remind me, as it usually does, that I generally prefer working on other things on my toons to raiding - four hours for two emblems of conquest. I figure if I wanted those (which I don't at this point) I probably could have gotten at least 20 in the same time period just pugging heroics. Or gotten at least 2-3 levels on any of my alts.
But, it was fun to get to know some people in the guild since this is a relatively new guild for me, so probably time well spent overall.
