I currently know 
grants a lot of AD in the early game in exchange of no mechanics whatsoever, but it gets to a point were you feel the need to sell the item lacks an unique mechanic and you can get better option for AD/CDR.
Build Path: UNCHANGED New Stats and Mechanics:
- +40 Attack Damage
- +10% Cooldown Reduction
- **UNIQUE Passive: **after killing a jungle monster or a champion your next attack or single target spell will deal 32 (+LVL = 50 MAX) bonus damage and reduces the armor of the target by 10 for 10 seconds. This bonus is doubled against monsters up to 100 damage dealt and 20 armor reduction against monsters (which would actually amplify the damage dealt to all of the Jungle Monsters, excluding the Epic Monsters).
PD: If you want a complete review of why the early jungle is a lot harder this season read this: http://boards.na.leagueoflegends.com/en/c/miscellaneous/0tgqZFaA-s6-a-harder-early-for-many-junglers?comment=0003
