Tracker's Knife is almost mandatory in professional play, giving professional teams enough vision to avoid most early-game danger. Bringing it in line would kill it in most games, so for now we're simply removing it.
NAIL (PASSIVE) : Now additionally grants 15% attack speed for 2 seconds after basic attacking a monster.
TOOTH (PASSIVE) : Burns for an additional 50 magic damage over 5 seconds (still steals 30 health over 5 seconds)
On-hit damage up. Lifesteal up.
With Krug and Gromp Smite bonuses gone, we’re upping both the damage and sustain on Hunter’s Machete (and its upgrades) to compensate.
ON-HIT DAMAGE :  ⇒ 25
LIFESTEAL : [8%] ⇒ 10 %
PAY IT FORWARD : These changes apply to Hunter’s Machete upgrades as well
Monsters grant more experience to junglers but less to non-junglers.
The tactic of a solo player abandoning lane to farm monster camps with their jungler (we call it 'buddy jungling') evolved in response to the 2v1 lane swap. Rather than sit under tower, zoned out of experience, top laners ditch their lanes for safer prospects. Buddy jungling is enabled by the 'comeback' mechanic, which increases monster experience for lower-level champions. Though the jungler and top laner are both constantly underleveled due to splitting camps, comeback experience softens the punishment by adding net experience versus a solo clear.
The casualty of this technique is the early game itself: buddy jungling puts eight of the ten players on the Rift into a pure PvE situation. That leads to an incredibly stale opening phase of the match and eliminates the lane dynamics many of League’s early-game champs (Renekton!) rely on to make their impact.
We're putting a damper on buddy jungling by removing the experience efficiency granted to the buddy. That’s not to say it isn’t still situationally viablhaving two people in the jungle can offer strategic valuwe’re just ensuring it’s a
ONLY FOR THE WORTHY : Non-epic jungle monsters now only grant experience to their killers

FARM RAZORBEAKS All Jungle items now grant 30 bonus experience on monster kill for each level higher the monster is than you
TIER 1 JUNGLE ITEMS : Hunter’s Machete and Hunter’s Talisman grant  ⇒ 50 bonus experience on large monster kill
TIER 2 JUNGLE ITEMS : Stalker’s Blade, Skirmisher’s Sabre, and Tracker’s Knife grant  ⇒ 50 bonus experience on large monster kill
HUNTING GROUND : Based on the above changes, total jungle experience rewards have been adjusted. Overall, junglers now get slightly more experience per clear while non-junglers get slightly less.
Just some slight tuning to make these a bit more attractive/easy to upgrade compared to just buying the component of your enchantment (Caulfields, Aether Wisp, etc).

now that's a knife
Tracker's Knife doesn't strengthen your Smite, but gives you a Sightstone-style stack of seeing sticks to seek out sporting stalkers and sneaky skirmishers, securing your squad's section of Summoner's Rift. Alternatively (for the alliteration illiterate) this augment allows illumination always, assuming your ambitions align with accumulating authority alongside your allies over your adversary's abode.
