That's actually different, and produces a different graph, with a wierd mathematical artifact of parry's usefulness dropping to 8% when used against a model with an equivalent WS.

Gotta reword if it's so easily misunderstood what I meant. To break this down, I meant that a defender can parry if he makes a successful attack back at -2 to hit (regardless of the attacker's hit roll). If the defender's WS is less than half of the attacker's WS, he can still parry on a roll of 6 if the attacker rolled less than 6.

Of course, we could just drop that last bit and let a parry roll of 6

*always* block an attack. This is for simplicity of the rule. The only time this would make a difference from what I posted above is when the defender's WS is less than half of the attacker's WS.

Alright then,

**Alt2v2** (hero's alteration of Alt2 altered a bit further

): if attack hit, defender makes an attack roll back at a -2 to hit: if defender's roll is successful

__or__ is a 6, the attack is parried.

With Alt2v2, the parry effectiveness is simple:

--- If the defender's WS is greater than the attacker's, he has a 33% chance to parry.

--- If the defender's WS is equal to or less than the attacker's, he has a 17% chance to parry.

Alt2v2 chance to hit through parry: (<WS Attacker>vs<WS Defender> <Chance to hit through parry>)

1vs1 42%, 1vs2 33%, 1vs3 22%, 1vs4 22%, 1vs5 22%, 1vs6 22%, 1vs7 22%, 1vs8 22%

2vs1 56%, 2vs2 42%, 2vs3 33%, 2vs4 33%, 2vs5 22%, 2vs6 22%, 2vs7 22%, 2vs8 22%

3vs1 56%, 3vs2 56%, 3vs3 42%, 3vs4 33%, 3vs5 33%, 3vs6 33%, 3vs7 22%, 3vs8 22%

4vs1 56%, 4vs2 56%, 4vs3 56%, 4vs4 42%, 4vs5 33%, 4vs6 33%, 4vs7 33%, 4vs8 33%

5vs1 56%, 5vs2 56%, 5vs3 56%, 5vs4 56%, 5vs5 42%, 5vs6 33%, 5vs7 33%, 5vs8 33%

6vs1 56%, 6vs2 56%, 6vs3 56%, 6vs4 56%, 6vs5 56%, 6vs6 42%, 6vs7 33%, 6vs8 33%

7vs1 56%, 7vs2 56%, 7vs3 56%, 7vs4 56%, 7vs5 56%, 7vs6 56%, 7vs7 42%, 7vs8 33%

8vs1 56%, 8vs2 56%, 8vs3 56%, 8vs4 56%, 8vs5 56%, 8vs6 56%, 8vs7 56%, 8vs8 42%

That does look good.

1. The rule is simple enough to implement and remember.

2. The base chance to hit through parry for equivalent-WS models is unchanged from official parry.

3. The effectivess of parry is greater for greater-WS defenders.

4. The extremes of the WS still allow for both decent chances to parry and to hit through parry.
