Warrior Enhancement Changes
Warrior -> Berserker: +40 AD -> +35 AD +10% CDR -> +15% CDR +10 Armor Pen -> Unique Aura: Nearby allied units gain Bloodlust and +10 Armor Pen. The context for this change is that it would help the team overall, but would not be a strong buff to the item or the champion with it. It would simply give the item more presence when the jungler came to gank, or late game during teamfights so it remains a viable part of the build.
As we all know, Season 5 jungle has gone through some major changes. From the camps getting reworked, to the build path itself getting reworked. As things have slowly changed, each of the enhancements has been given something to make it unique to itself and make it more interesting... with the exception of Warrior. Cinderhulk has Immolate, Devourer has on-hit damage and can become "Sated", and Magus was here more recently changed into Runeglaive. I think it is a shame that AD junglers can't have something with a tad more depth, and I think these changes would fit that very well.
