crusader and imp 2h in ret take 6 points total for 12% damage (may be more than this due to additive v multiplicitive). its a talent intensive build, so why would anyone take righteous vengeance for 5 points when 5 points way earlier in the tree will net 10% total damage increase (even buffs judge damage by 3% due to 30% mw).
considering i also want to ditch 18 points into prot for 30 second stun, why would i ever get some of the high end ret talents, mostly fanaticism and righteous vengeance. i exclude swift ret for its mainly pve focus.
