Yarr! Tools :: Warrior 8472
This looks like one of the better possible DW fury builds for WOTLK. I haven't looked into the math for titan's grip, and if it isn't that great, this is the way to go. You get 5%crit from axe spec(+plus crit damage) so u have more bloodsurges and also u get more sudden death procs to use. You'll have Bloodthrist, Instant Slam, Sudden Death Execute, and Whirlwind to use as instants (prioritizing the most important to least skills you should use, I don't know how bloodbath is going to work so I didn't put that in there). You'll rarly have to heroic strike with all the GCD's you'd be using, that means less bonus threat, threat isn't a issuse though.

Titan's grip build, axe spec is the better choice because more crit = more instant slams, which shouldn't reset ur swing timer. You could maybe drop the 1 point in Furious resolve and put it in Precision.
