[GAMEPLAY] Stormrazor is ignored when backstabbing.

Expected behavior:

• Backstabbing someone with Stormrazor should use Stormrazor's crit modifier (160+)

Actual behavior:

• Backstabbing deals 130% damage, Stormrazor doesn't get applied
• Normal Stormrazor crits (not backstabs) deal more damage (160%+) than backstabs

This kind of defeats the purpose of this item, even if it might be a good buy on him.
