Making Poacher's and Stalker's Worth the Buy
Poacher's Knife now has its benefits trigger on any monster camp, not just the ones in the enemy jungle. Additionally, give it an OnDamage true damage buff to you that only triggers on Monsters. This would cement it as the item to buy if you want to improve your clear time and generate gold faster, but don't really care about the extra sustain offered by Ranger's.
Make Stalker's get some degree of cooldown reduction if you get a kill or assist on the champion you smote with it. That would help to better emphasize its role as the ganking upgrade.
