Why is Poacher's Dirk even an item?
I can understand the reason to put the item in -- it allows you to gain stats effectively for "free", while allowing the Lethality to scale up with levels (which come with time.) The main problem is that it's entirely unnecessary. It encourages laners to roam and pick up an extra camp for the gold, but that only works if that laner is ahead. The only time you would be able to leave lane without giving stuff up is if you've pushed your enemy laner to tower, and have a comfortable advantage.
But then, if you have an advantage, why don't you have the additional 400 gold required to get a full Serrated Dirk? The whole intention of the item is paradoxical. It's meant for people who don't need to buy it.
