Reset inactivity timer when an attack is blocked

[GrafBlade]

As the inactivity tracker uses damage as one point showing activity, wouldn't it be possible then to use damage dealt to cades as well? A dead Shielder being tomed in should be able to manage finding a cade on his way to the shielding spot or to corner Odin and simply hit it while walking.
Of course given the case, that the activity tracker might be bugged and does not count moving around.

(Not sure if it has been suggested so far)
