Ideas for Higher-Resolution Combat - Feedback Requested

[Gigermann]

What I came up with for "unexpected" attacks:

Deceptive Attacks and Feints are more effective when originating from a "non-standard" attack type (FREX, kicking or pummeling when using a broadsword), and the defender is unfamiliar or inexperienced; if either succeeds, add an extra -1 to the target's defense penalty. Treat as "Familiarity," B169. An appropriate Style Familiarity Perk grants familiarity with all such ruses normally associated with that style, in addition to providing its listed bonus, as described.

Precedent: "Reverse Grip," MA112. I also allow the same for left-handed fighters against right-handed, or vice versa.
