I've read through all the BIS lists and the related "should I break my T15 2pc" threads. All of them reference having 2pc reg or heroic gear.
In my situation one of my pieces is reg and the other (head, upgraded) is LFR. My UVLS is also LFR (upgraded). Tonight http://www.wowhead.com/item=105808#comments dropped for me and since it's a huge upgrade I need some advice on whether I should break up my 2pc or hold onto the 559 head until I get T16 2pc. My gut tells me to go with the 559 head and break it.
I'm not real confident in my T15 to T16 gear transition yet when set bonus's are involved. I know brother Drye and others aren't crazy about T15 bonus's so I wanted to ask for advice.
