The person who reported you did a glorious TLDR of your post, highlighting the various issues with it:
"I'm using a bad spec but that's okay because my raid is bad and I'm still top DPS. Not sure why I'm telling you all this, I just thought you should know.
Oh, by the way, I was wondering about that new playstyle people have been talking about possibly being worthwhile for the past half dozen pages, but I don't feel like actually finding where you started talking about it. Someone please repost a summary of the last half dozen pages. K thanks."
Ive always been Frost 2H Spec (I know laugh all you want) for our 10man even know it's not optimal compared to DW (5k Difference) and 2H Unholy but I'm always top DPS for our 10man group and we progress fairly quick (FL Heroic 5/7 and DS 7/8). Plus we've had bad luck on 1H weapons dropping.
Is there a rotation difference for Masterfrost between 2H or DW? Also does the BiS gear change from normal Frost Spec?
