Just like the topic title says.

I know that Double Team does (?) but I am not sure about the others. It seems like you could get a crazy high Parry.

(For that matter, do they apply to Feint? They are all WS Tests)

Simple answer...no...

Simple answer, yes.

The bonus granted due to craftsmanship applies to all WS-tests utilizing said weapon.

For Hatred, it only applies if used against them (the Hated enemy). The way that's worded, I would surmise that it would apply to all offensive actions, so no, not on Parry.

Think that the only benefit that Parry has over Dodge is this kind of bonus (from using a Sword, from using a Best craftmanship weapon, Double Team and so on).

Also the possibility of counter-attack if you have the proper talent.

On the other hand, Dodge can be used against ranged attacks!

I stand corrected. In the older games it only added to attack roles.
Though Hatred would not give any bonus in my games.
