If hysteria is up when you cast rend, then your rend will benefit from it. Is it worth it? Well your buffed crit chance is only 85% without anatomy, 88% with, while the cap is 93%. The 10% buff is watered down by brawler (30%) and battle rage (15%), so the actual boost is about 6.8%.
I guess the best way is just to test it out. Personally I'd rather not depend on a slightly randomly active buff to be on to kill trash reliably, whereas extra crit chance should improve consistency by bringing me closer to the crit cap.
You might also want to try WW/rend with a skorn. The high base damage will do wonders for your rend damage.
Thx for the reply. Yeah I'm just testing hysteria, I haven't done enough runs yet to say it an improvement in xp or not.
In regards to your advice about the Skorn, I did originally buy and use a Skorn with my first build and for the life of me I could not keep my Wrath up to save my life it was always falling off and I even added attack speed to my gear afterwards and still couldn't keep it up.
So at that point I decided to go with a 1h axe and EF and now Wrath never dies and I don't even have to look at the buff to worry if it will, I can rend and ww all damn day. Yes I know I/m probably the worst barb in the world for someone who can't keep wrath up with a skorn.
I've seen it done, Moldran was the one who I used as a reference when I built my barb and he is some how able to keep wrath up most of the time with a Skorn. Moldran says he runs a 1.67 break point to keep his wrath up. I actually had more than that and as I said I still couldn't keep it up. I honestly don't know what I was doing wrong. I even went back and watched his game play VoD's to watch his cool downs and see what he's spamming and when, either way I still failed at skorn with wrath.
Any tips on it would be great.
