Tirok, You're completely ignoring the changes to SR, since it no longer multiplies AP, it becomes a very weak stat, and Str is only better because of Kings/SotF. Agi was already a fairly potent stat since high crit helped steady cycles, and now that Bleeds also crit it becomes even better.
Duskmourne, just a couple things; Mangle>SR>Rake is the preferred opener. You lose more damage not having SR up ASAP than you do by spending that extra energy early on. After that, what I do is Shred > TF > Berserk > *. This lets me get up a Rip and then another 3-4 cp before I need to SR again after that short opener, and then shred til 5 and FB easily. You mentioned wanting to shred 3 times per rip because of the
[Glyph of Shred], but earlier say you'd use Rip/Mangle/Berserk glyphs, it's debatable which to drop for shred unless you have an arms warrior, but I'd drop the Mangle glyph anyway since it has no bear utility.
