I liked this latent idea a lot too. Giving that to a different equipment piece fixes the dps issue because a th dagger will probably be sucky in comparison to what's the best out there on dps terms. Also, a ring doesn't affect our dps like a weapon choice does, and there is also the option of giving it a secondary dps stat. I mean, even if we gave such stat to the weapon, its damage and delay will be what make or break it.
