I saw one player doing his "OWN" one-man-team very-short-cycle exp run!!! I joined him every time. The weird thing is... he is still looping around even all the enemies around him were dead! I helped him to kill enemies... Then he left and then created new game for the same map (that's why exp run). I joined again. This time I didn't help him to kill enemies and he was on the same loop (sometimes he kills all enemies sometimes not before leaving, sometimes he gets drop items but I am sure he's liquidating it before he leaves because I saw "busy" status)... I observed this over and over until I realized that his move is just ONE CYCLE!!! Very funny but what I concluded(or hypothesized) is this: he recorded the clicks of his mouse on his PC by some macro recording so he can gain exp even without physically playing PL.. OMG but well, that I think is wise other than using elixir which I am addicted to.

BTW, map he played was the first map of Nuri campaign!
