Actually I'm probably being unfair to sword spec, since unlike your earlier assumptions, adding into critical strikes will, in fact, make a bigger difference for sword spec than the other rotation.
Ah well, I'm too tired to try and back of the envelope that change today. Peace.
Yes the maximum DPS spec for 2 Hand DPS is gonna be 21/40 (Not having access to rampage is better for lesser gear) 20/41 is more of a max gear spec during the later gear as in BT/Hyjal which I assume you are.
20/41 is the spec to go for maximum personal DPS because it scales so well with gear, I personally have not speced it in a serious raid since I am the only MS Warrior in the guild.
But yeah I am tired as well might have over looked something but Ill get back to it when I can
does any know what the 20/41 build looks like? Can you please post them here? And why when i click on the links, the builds are not quite what they are? any1 who can shed light on this matter? many thanks....Im kinda new to this game so there :P thanks
