A player in one of my games a an interesting strategy.
Long story short, in a ranked game I select jg wukong right after the person in front of me picks warwick top. He then says he is going to take smite top with devourer. He was very polite about it, so i was pretty sure he wasn't trolling. He told me to trust him. We go into the game and he explains how he can have the scuttlers, which i agree too. He then tells me that what he's about to do isnt true, and that he will clear it up later. Because two of us had smite, he says in all chat that i am trolling. At first i was confused, but i got it. Because he said that I was trolling, which we later explained to the other team that i wasnt and not to report, the other team thought "hey, their jg is trolling and bad" so they all pushed lane. Because of this, I ganked so hard in every lane that their jg afk'ed and their mid gave up lane and said "mid's open". The other team started a flame war between eachother. It worked so perfectly. Whoever that ww is, for that game, he was a genious xD
