Junglers, give me advice?

I've been putting jungle as my secondary recently, and I run into a problem fairly often. My mid laner will lock in a or or somesuch, and top lane is an ad bruiser like or something. How do I as a jungler bring ap to the comp? The only ap jungle I've seen in the last 30 games was a jungle, and she got counter-jungled really hard by our , so I wasn't sold on the idea. I can't play to save my life, and if I pick I find I'm at the mercy of a or for the first few clears.

So my question is, who do you lock in when the comp needs ap? Do I just need to git gud on and ward more, or should I just go as usual and try to stack through the armour stack?

P.S: While I have junglers in here, what happened to ? I forgot he was a champion til I was scrolling through my owned champs lol, I never see him anymore.
