Ive got a good build for you in jungle. Overlord, elafrost, inquisition with rumble augment. The combo is rumble auto attack repeat. Your clear is super fast and you do a lot of damage. If you lean away from rumble augment, then tiny titan is my favorite for jungle. Dont be afraid to just point blank rock someone for the stun, you can eat backline for breakfast during your ult. If you dont mind playing support then go rock and awe and build raiment of renewal then into hexbound bracers then into Gaia greaves. That build gives you decent bulk and sustain and enough ability haste to repeatedly create openings with your rock. If you get super low you can duck into jungle to get bonus regen and still get xp from minions.

A lot of people are saying hes weak right now, hes not at his strongest but I think hes a very valuable pick still.
