Games : As a jungle how do i pick/play against a tank comp?

Thanks to the buffs made in both crowd control as well as health/tank items being easier to build. There have been a lot of people building tank comps like "Cho'gath mid, Sion jungle, Maokia top , leona support, with a long range adc or high poke like corki or jinx". i have had a very hard time time playing against comps like this. My main champions at the moment have been Volibear, Rek'Sai, Nautilus and Master Yi.

1. What champions are best against these comps?


2. How should I play against them as well?

Currently I build according to what the enemy's biggest threat is and/or on how far ahead I am compared to that threat. Quick example is on Rek'Sai I rush hydra if they have a fed ap laner then slowly build visage but I change that to something more economical if i am behind.

3. If I should change how I itemize how should i change it
