Have you tried the 0/32/19 fury prot build? The 11/5/35 worked in vanilla but will never keep threat against the higher dps playstyle of classic.

I do not have a team like yours so cant help directly. I am trying out fury prot on my 4xWarrior/1xH.Paladin team.

You have engineering? Going to need explosives no matter the build. If alliance you might also try H.Pa for salvation.
