Skitter

I've done some super rough napkin math on guildies proc rates, I'd say 6% on Viskag (I'm erring on high side, might be little lower). Where would this put it for warrior MH weapons now? Edit: have been trying to find nost info on proc %, having no luck

From a tanking standpoint, you'd DW so rarely that there would be much better specs (for max threat, shield slam for instance). From a dps perspective, you're giving up flurry + BT, not to mention impale, and your main rage dump would then be...heroic strike? Again, there would be much better specs. Even for a hybrid dps/tank, you'd be much better to go deep fury.

As human using BRE but moving to DW soon (have Edgemasters), is it safe to say based on this that Vis'kag is the best weapon to pick up when possible? In ideal scenario, would CTS+Maladath not be superior?

I've tried using the spreadsheet, but get a bunch of boxes with "NA" and error codes. Has anyone else had this issue?
