Nah, the biggest thing is missing IR Decimate spam on adds. But as Canadane mentions, doing the ghost cheese will at least align your IR with the upcoming knockback ghost. I still know at least 1 War tank that refuses to do the cheese because of his connection probs, but in general your just trading personal dps for raid dps. If you're going for top logs than you'd need to make someone else do the cheese. Otherwise just suck it up and do it for the group :P
