ARURF is the most awful gamemode ever introduced in league.
NOBODY gets satisfied. The reason why people played URF is that they can fulfill their wish of playing whatever they want. Not because of balance and a few OP champions. Making it random does NOT solve the solution, and it leaves nobody satifsfied. ALSO there is this accursed possibility that you get picked melees into mages and be swiss cheese at their mercy. Having responsibility in your picks signs a agreement that you will face your fate. This is just a horrible gamemode.
