An idea to make Poacher's Knife more interesting

I think Poacher's Knife is too unreliable and doesn't give enough benefits and it's why it's not used.

I think it should be more punitive than it is now for the ennemy jungler and at the same time give a small benefit in your own jungle.

So, this is my idea : "When you smite an ennemy camp, it will take 50 more seconds to respawn. Cooldown of smite is reduced by 10 seconds (even in your own jungle)." That's just the idea, I don't know if the gold and MS bonus should stay or if the numbers are too low / high but I think it would really make it more interesting and more powerful.
