Antigoth, you're right, I'm not particularly comfortable with this ruling. But I'm not trying to change anything, I'm trying to understand the logic behind it. This is purely an intellectual pursuit for me. Nothing you've told me is wrong so far, I'm just asking a different question to the one you're answering.
At present I'm trying to determine exactly how much of the consequences of blocking are contained within the blocking effect. Does it include the damage being reduced to 0 if fully blocked, and reduced to half if partially blocked or if the throw keyword is involved?
