Parry Missile Weapons as Technique

[Kalzazz]

I have at times rather not liked how Parry Missile Weapons works as it is its own separate skill as opposed to part of another weapon skill

For instance, if Mia the Swordmaster wants to get good at parrying arrows and such with her sword . . . . her sword skill has no role in it. And so she buys up Parry Missile Weapons. So now she can parry arrows with her sword. And with her gauntlets. And with a spear. And so on

But while she can parry arrows fine with gauntlets or a spear, she can't parry anything else with them (assuming she is focused on sword use instead of spear use or brawling or such)

Anyway, characters pg 212 has Parry Missile Weapons, and Campaigns 376 has Parrying Thrown Weapons

Campaigns applies a -1 penalty to parry most thrown weapons, -2 for small ones

Parry Missile Weapons gives +2 to small thrown, +4 to large thrown

So, if +4 for large thrown vs -1 for large thrown, one could guesstimate that a hypothetical Parry Missile Weapons Technique defaults to Parry -5

So, would a Hard Technique defaulting to Parry -5 be reasonable? (or a technique in general)

It would be cheaper for the most part, but balanced due to being for 'this one combat skill' instead of 'parry missile weapons with almost anything' I'd think
