I have to admit to loving the fact that my 25man raiding team is one that newcomers join and say "Wow, that's a lot of Shadow Priests", rather than being the token SP. I know a lot of folks would prefer to be a unique snowflake in their raid, and yes, in theory, it will make drops harder to come by, but I like being part of a subteam in a raid. I blame my 40-man raid and its class-specific Team Speak channels for making me this way.
Thanks to Mind Sear, we make very short work of the trash. 10k crits on that if your procs and the pull allow. Having come from raiding on my Boomkin, who only had great AOE for 30 seconds every 3 min when she could use starfall plus typhoon, it's a world of difference.
So far, the only scary part has been learning the MCs for the Razuvius fight. MC just hasn't been something I've played with a lot. I got the hang of it, and looked up the macros for the next go round so that I can announce what I am doing without having to type/think about it, and so there will be no debates about whether or not I used my bone shield ("It's on CD, so that's pretty clear that I popped it regardless of what you see, k?")
Last week the 25man team couldn't get together the right group for finishing off Thaddius, so they called it. I know it was a tough call for them, but if my choices for the evening are to wipe on Thaddius for an hour with undergeared/inexperienced folks or have the raid called and get to bed early, the former would not be my choice. Signups for Saturday look good though, so I am hopeful we will kick as much butt as we did the week before.
When thngs have gotten me down in the past, alliance side, I used to sometimes think to myself that maybe I should stopraiding. But upon further reflection, it was always clear that raiding is what I always have loved doing, since I dinged 58 3 years ago and got hauled into MC due to our raid being short on healers. The key is realizing whom you want to raid with. Happy to have found such a great group of folks -- both in guild and in the scrub raid -- with which to do so.
