Looks like BC raids are getting nerfed soon. See the blue post here.
I think the word ‘nerf’ is overused and I typically associate it with whining, but this time, it seems apt. The raid bosses are being made spongy and having their pointy edges removed so that raiders are less likely to get hurt. Wonder if they’ll shorten that Karazhan reset timer sometime soon, too, then. (That would be nice!)
