And you keep mentioning "what if it doesn't proc". And? That fact that the proc exists places it above a piece of gear that doesn't have that proc, when used in the situation you are equipping it for.
What if a mix is the best? What if it doesn't proc? What if it never procs? What if it always Procs? Its RNG. You don't design encounters based off what can or can't proc. Sure it will help, but its not something you can rely on.
