Silver ult doesn't use correct Merc Mag damage.

Set up Silver's gun to about 120% spirit damage on merc mag, but it seems to do only about 26% spirit damage in wolf form.

Was just about to post this, it seems to be based off a universal value or based off of her gun per-pellet damage making it useless

Its definitely using her pellet damage if you run the numbers, IMO should be based on claw damage tho.
