Your posting style says elitist jerk, but your use of "ur" and failure to properly use apostrophes demotes you to just plain jerk.
Hmm... 4pc of T7 gives an extra FS every 10sec which scales with gear and buffs that comes from your other slots anyway. So its not a flat out 500 and should always be the best dps till I do not know what Obliterate rotations comes up. And please enlighten me on how bad T7.5 is for frost DK? I believe the shoulders and pants are pretty much the best for us, helm and chest its really ur preference. So how much more stats you gain from them? Please enlighten me. Frost DKs have 2 main attacks, its FS and Obliterate or maybe IT for some rotations. If your OB dun generate enough RP, you need to IT more often. FS is our best skill come 3.1, arguebly better than Obliterate (depending on how well ArP is come changes in its mechanics). I would wager that whichever rotation produces the most number of FS wins the dps race. I merely suggested my opinions which I knew would not be accepted likely. I stated a factual problem which we have to face in the future. The problem is, Obliterate centered Frost builds depends heavily on 4pc bonus that its existence to stay competitive is being threatened by the evolving WoW come T8 and patch 3.1. Its only a future problem I wish to bring up and prepare you guys for it. WoW changes, rotations change, just like how hunters have to change their rotations and 1 button spamming from BM to survival.
