Doesn't buying Poacher's Knife give your opponent too much information?
By buying this item you're straight up telling the other jungler "hey I'm going to be invading your jungle, so ward up" And it's not only saying that you want to counterjungle, it's saying that you HAVE to in order to get a return on your investment. You can't just switch back to farming your own jungle without effectively wasting money.
This kind of applies to all the new machete upgrades but especially Poacher's because you want to keep your opponent in the dark when counterjungling.
Maybe the machete upgrades shouldn't be visible to the enemy?
