Mostly jungle. Likely 8:2 jungle:top ratio if I (or the client itself) actually kept track of such statistics. Need more practice with him top outside of surefire counter-picking.
Also the funny thing is Mundo is like, the one melee Trundle doesn't really want to face top during the laning phase (soaZ probably aiming for the Shyvanna match-up) and Gambit still gave him a kill for it to not matter anymore.
You need the right comp for him.
I guess that makes sense. He gets peeled easier than a banana.
Also if renek/shyvana/vi weren't raidbosses I'm sure koggles would see a lot of play as well.
He does get kited relatively easily, but his criteria for an ideal team composition aren't that steep honestly. More dependant on what the enemy picks; pretty much a no-brainer against Shyvanna, Renekton or Vi for instance depending on the role and especially if the enemy opted for supports like Taric, Leona or to a lesser extent Thresh on top of that. Beyond that he synergizes really well with a good number of currently popular champions and he's a massive douchebag with the likes of Karma.
His 'best' time has come and gone though, back in Season 3. He would've shined if people knew about his strength during the Vi - Xin - Jarvan - Volibear - Susan jungle days, never mind when Nida/Lux/Jayce poke comps were all the rage.
