Please consider disabling smite in some Summoner's Rift Rotating Game Modes
This mostly applies to ARURF and OFA but there might be others I'm forgetting.
Anyway, gamemodes like these should be nothing but some cheap fun, and for the most part they are. Unfortunately with smite being available it's not that uncommon to have games where someone on your team will insist on jungling, only to have the enemy team running a 2-man top instead. This combined with the fact that you can't really choose who you're playing has led to some of the most frustrating gameplay I've ever experienced in League of Legends.
