So I'm about to enter Ulduar 10 for my first time

I was wondering I heard there was a lot of non-duh mobs there, and right now both my specs focus on maximum threat for duh mobs. Should I respec for the raid with the 5S 3R 3V build? Or is it not that big a deal?

Ulduar is pretty old news, as long as you can hold threat off of your raid members in any spec (you should never have to spec for threat in ulduar.) You will be fine.
