Yeah, I definitely don't play as much as I used to but I still do maybe ~1-3 ranks a week. Usually Friday or Saturday I'll have a few drinks and decide to do an aram or two and a ranked or two. Been pretty much playing Jungle/ADC lately but honestly sometimes I Just select Jungle/Mid so I usually get to jungle 24/7. Cho'gath & Rumble are my goto junglers right now, just a ton of fun, off-meta, but people don't expect it. Lot of times I do almost full AP on both of them as well, maybe getting a tanky item if I'm falling behind a bit.
Cho just brings insane Dragon/Herald/Baron control since by level 6 you have like ~1500 worth of True damage. Plus, at least in Gold players still can't really dodge cho's rupture that well, so rupture + silence + feast is usually a kill for me or my laner. Rumble is a bit tougher early on but after you get runic echos you clear the jungle like a freaking monster. Plus once you get 6 you just pick top or bottom and blanket your ult either ontop of them or behind them so they pretty much have to flash over your ult or die.
Cho = EQEW usually, or EQW if you're going to lvl 3 gank. Max R > W, then honestly Q or E can be switched. E if you give up your blue more so you can still farm jungle super fast otherwise if I"m being selfish and taking blue I Just max Q for more bursty damage.
Rumble = Max R > Q, then depends again, speed/shield (w) is awesome early, especially if you don't want to build much defense, but having the harpoon for ganks is strong. Although usually with Ult + 1 harpoon hit (even lvll 1) they should die.
