What would be better for players 8, WW , Zerk or Frenzy?

Atm rolling with Frenzy with 2x Grief PB and feelin like I'm lackin a bit... Although I'm using enigma and not fortitude..

Will Fort make a huge difference with high player level?

Thanks

With grief, guils face, and highlords and you should melt faces.

ww is 2.5fpa, other skills can't compete
forty normally doesn't make a huge difference
using forty (300ed) over eni(~100ed) increases your dmg by (300-100)*100/(total ed + 100) percent
for example if you have 175ed ww 175ed mastery 600str 350ed loh 200ed might, forty over eni would increase your dmg by 20000/(175+175+600+350+200+100)=12.5 percent
eni is the armor of choice
