"With Krug and Gromp Smite bonuses gone, we’re upping both damage and sustain on Hunter’s Machete"

It didn't need a buff. Only the machete junglers were taking a harder beating from the monsters. It was to the point that was probably the better clear on some single-target champs (when testing solo in customs).

Talisman will be fine still. Machete was sub-par to it as it stands.

Yeah, Talisman gives you sustain for every thing you hit, while Machette was single target. I would say talisman is good right now, Machette needed to be brough up to its level
