My guild, like many casual-friendly guilds that don't have a set 10 people for every raid, occasionally has trouble with consistency.
Even though we may have most bosses on farm status, we'll still wipe repeatedly to them some weeks, which seriously hampers our progression time.
Tonight, however, was the first time in awhile that I've felt we had a brilliant run - 5 bosses down in Blackwing Descent (including Atramedes, a new one for me because I missed our first kill), with most of those a one-shot.
I'm definitely looking forward to tomorrow night's raid - the Ascendant Council will hopefully go down, meaning we'd just have Cho'gall and Nefarian to go... and I'd really like to clear them before Firelands hits, just to say we did it before the nerfs kick in.
(And before anyone says "Sinestra", I think it'll be pretty difficult to get through an entire raid's worth of heroic mode progression to get to her before Firelands hits :P)
