Seeing this huge thread, I more and more believe, that hidden characteristics are most important for a player. Else I cant explain, how always the same teams get trolled, while my team didnt ever have a single clear troll (season 20, missed few of them).
Also, to describe the troll most use only match statistics and overall q. Thats not enough, at least needs to compare white skills. If I meet the same overall q with high greys, I almost always "troll" them with a high scores win.
