I only left the DG/DS points there because he had the ability in his base build and thus might have a reason to find it useful (I didn't change that part of his build). I basically just upped his threat by redistributing other points. It doesn't happen to be my exact build, just a build well suited to the problem that he presented (trash threat problems).
Some like divinity, some like DG/DS. I don't particularly like either and use them just create enough points to get further down the tree. Pre-ulduar divinity is going to go mostly to overhealing. Honorshammer's build (which is perfectly fine) is essentially the same build chosing divinity over DG/DS.
To comment on your proposed build, reckoning won't provide you the threat output of the same points in the ret tree. Not taking a point in improved judgement means that you're not doing a 9696 rotation and that nerfs you badly.
If you aren't higher than me in total damage done or total healing done, all comments will be /ignore'd
