Tracker's Knife-- What's keeping it back?
Hello, VentusDragoon today on his biweekly or so questions about your thoughts on the game. With the release of the new queue, I've found myself going jungle a lot more often than just support as I usually do, not that I mind. I play various junglers, but most of the time when I go tank jungle (Sejuani, Zac, Nautilus, etc), I buy this nifty little item in the shop called...
The Tracker's Knife! 
This fancy little dirk not only gives you the stats of your enchantment of choice along with the base jungle item, but gives you a free sightstone to boot! Lee Sin mains cry tears of joy and the game becomes a much more warded place!
...
Except they don't. And the game doesn't.
Even though the concept of a free
attached to your jungle item seems incredibly helpful to help vision on your team, as well as providing a much easier way to counter-jungle, I've noticed that the junglers using it are few and far in between. Almost all damage junglers bring along the shiny Skirmisher's Sabre
, while most others take the true-damage-slow for Stalker's Blade.
You would think that ESPECIALLY Lee Sins would bring along the Tracker's knife for the larger amount of wards to jump to, but it's exceptionally rare to see anyone take it, oddly enough.
So, my question to you all is, what do you guys think the problem is? The stats with enchantments are exactly the same, so what's so much better about the usability of Stalker's Blade and Skirmisher's Sabre than free wards? What are you ideas for how this may be buffed/adjusted so that it's a bit more popular? I'd love to hear all of your ideas!
Have a good day everyone!
