in champion select, wukong instalocked but said he didnt want to solo top after i locked in lee sin. this was ~10 seconds before the game was starting so everyone clicked random champions (xin and malz)
then we get in the game and vlad and nid are both mid, wukong ended up soloing top anyway against their zed, and xin and our zed went bot against their renekton. xin went mid after and decided to go ap.
When people pick solo top champs and then say they don't want to solo top, you ignore them and make them solo top anyway. Generally works out better than putting them anywhere else, worst case scenario you lose a lane that didn't have a great chance to begin with.
