I see most high rated Warriors are using http://wotlk.cavernoftime.com/item=38948 over http://wotlk.cavernoftime.com/item=44492 but to me 400 ap seems vastly superior to 120 arp.
Is berserking worse because of the armor reduction debuff? Did smbd calculate how much ap is actually lost because the debuff is interfering with http://wotlk.cavernoftime.com/spell=61222??
