My guild headed back to raiding last night (seems a lot of guilds are taking a vacation lately, with the patch and the expansion giving a one-two punch to the PVE game), and while BWL wasn't quite ready for us-- the Razorgore orb was bugged, and our MT couldn't see a pet bar for him-- we finally got back in the groove in MC. We'd been at a loss with new specs and a lack of our usual mods, but tonight, with various means and instruments, we were able to finally down some of our old farm targets and pick up some epic gear.
Decursive, as I said last week, was the big one. Apparently it was number one on the devs' hitlist, and for good reason, because it definitely took a lot of work out of cleansing decurses (like the one Lucifron throws out). But we've found alternatives that are "good enough." One of our mages now swears by Grid, an addon that works with 2.0.1 (I haven't tried it, but it comes highly recommended). And even more people benefited from this macro, posted in the Forums. It seems that if you create a macro that says "/cast [target=mouseover] Remove Lesser Magic" (or whatever decursing spell you want to use), you can then run your mouse over players or their raid icons while spamming the macro button, and you've got a reasonable facsimile of what Decursive used to do. In fact, this is even better-- Shaman (like myself) can create a mouseover Purge macro, run your mouse across a group of enemies in PVP while spamming the button, and never have to put up with a buff or renew spell ever again.
Speaking of my Shaman, when I asked for help last week, you all gracefully answered. I was extremely frustrated with the changes to addons (I lived by all the extra info redHeart gave me), but when I finally tried out and used Clique, I finally felt back at home. It's simple to set up and use, and makes things almost as easy as they were pre-2.0 (the author even has a video up showing how simple it is to use). Finally, the brand new version of CTRaid, 1.621 (I think that's the third version they've released since the patch) finally gets rid of that extremely annoying "clicking" noise the patch added to raids. A few things are still bugged in a few raid instances, but finally, raiding is getting back to normal.
