No. She would never fit in the jungle
offtopic: just had a caitlyn jungling for us. oh boy we lost.
Not very effective, slow clear you lose too much hp early.
It's possible. I've tried. I've seen Stonewall do it also. She has better sustain than other AD junglers. Spellvamp op.
Would I use her in a team comp? Maybe if top and mid was AD like Khazix and Jayce. But there are other stronger choices like Diana which is a really strong overall jungler with sustain, clear time, and gankability after 6.
Overall she isn't bad in the jungle. I tried it and I cleared whole jungle without using all 5 pots. It's just her gank is so reliant on charm that once that charm is gone, you're just shit.
It's OP ...............................if you were a smurf..
