jungle karma
With the changes to the ap jungle item and the changes to her W (allowing it to be cast on monsters) jungle karma is again something that works relatively well. Her speed and sustain are both good having a shield and 40% missing heal, and her first clear is doable but starts to shine post lvl 3 and scales really well.
Gankwise she is ok u tether-shield and almost always get the root add a r-q on them and they should be dead without flash, assuming fallowup normally does like 50%+.
power farming is possible but like always in the jungle not advised i went gromp-blue-red-krugs-wrath-wolf-gromp and never really fell below 50% hp only caring about the dropping mana when blue ran out.
buildwise i just go jungle item ap (i always go wards but can go speed) then it matters what u want, i think cd boots -> ghosts -> banner -> Rylai's -> pen or just try to be a second mid with deathcap and marellos
not sure how bad an aggressive jungler could get, would be the only problem that i can see but you become fast, and should poke and run
