OK nvm, discovered it myself ...
For those interested go to Demonbuddy/Plugins/Trinity/Combat/Abilities open WitchDoctorCombat.cs, delete lines behind && so u get
"
// Haunt
if (CanCast(SNOPower.Witchdoctor_Haunt))
{
return new TrinityPower(SNOPower.Witchdoctor_Haunt, RangedAttackRange, CurrentTarget.Position);
}
"
You're welcome!
