Not always. I have a 8-1 win rate on Maokai at the moment, and I never troll. I never int, I never do stupid stuff to give enemies an advantage, even if I want to intentionally lose a game. (I have a smurf account that I wanted to be bronze 5, but I still couldn't troll to lose the games. I ended up doing 7-3 in my placements, ending up in G4). The only loss I have on Maokai is vs a Jayce, where I got ganked 3 times in the first 5 minutes by a Shaco, losing my TP and Flash in the process and dying twice. I couldn't escape the gank, since Shaco becomes invisible and Jayce is just too strong. Afterwards, Jayce was just one shotting me even if I was under tower, because he was level 7 and I was level 4 with 30 cs down.
Now, I had two choices. Stay in lane and die whenever Jayce felt like it, or stay in base to avoid feeding. Some games are just that bad, depending on the match up. The most OP top laner at the moment got fed twice in the first 5 minutes so I virtually had no chance in holding my own. I ended up like 3/11 that game I think. It's not that I wasn't trying or I was trolling, but I couldn't just to anything.
