Ack, ok, need to revisit this wording, but the idea was that a Quick weapon helps with the DEX roll the first round of combat, regardless of opponent’s weapon. Essentially a -X modifier to the roll. Maybe something like:
Quick X: When determining who acts first during the first round of combat, treat your DEX as being X higher.
