My name is Cernunnos, I will love you like no other, I have died a thousand deaths, each time I died I thought of you.
You cant use raging blow or wild strike; and really all casters bypass 100% armor anyway, so the shield is rather useless in PvP, and its not like you are tanking as fury in PVE.
When you see someone in a thread making the same canned responses over and over, click their name, click view forum posts, and see if they are a troll. Then don't feed them."Gamer" is not a bad word. I identify as a gamer. When calling out those who persecute and harass, the word you're looking for is "asshole." @_DonAdams
I think this is where you are remembering Wow as it used to be. There is no "Get the Shield Slam Talent" anymore. If you want shield slam, its only available inside the Prot specialization. If you want Titan'sGrip it is only available inside the fury specialization. They are mutually exclusive. The talents are all flavors (the level 15 talents are 3 different ways to use charge).
Using the 2H to do serious damage has a couple issues. Hit and expertise are going to mess with you a lot. 1 big hit is great, but when you miss the next 2, kind of sucks. Also, 2H's get an automatic 10% damage reduction when being used in Titan's Grip apparently to level out having 2 giant weapons against other dps specs.
Think of it this way, for whatever reason, Single Minded Fury (2 1 Hand weapons) is higher dps than Titan's Grip (2 2H weapons). The back end math on Titan's Grip nerfs a lot. In Real Life a giant 2H weapon would likely do more damage than a smaller 1H weapon (assuming you were strong enough to swing it) but Wow math means that isn't necessarily the case in game.
I want to admit, this is a Fun idea. I actually tried it in early wrath just for looks. But the new class specialization system makes it more of an RP idea than a viable spec.
What a shame; if it weren't for the talent changes, this probably would have been an awesome build.
