The Fix for Riven
TL;DR: I do not think I have ever seen a single champion like Riven in the League of Legends. This isn't a QQ thread, but no champion who is 0/4/0 and down 50 CS should be able to 4v1. Yes there were some stupid plays made on the part of my team, however, if any other champion was so thoroughly shut down they wouldn't have been able to do so. This issue stems from her three AOE physical damage abilities that have great base damages and great scaling, and also her shield that scales as she builds damage. 100% of Riven builds reach the 40% CDR Cap with their first two items depending on build order, creating a high damage shield that has a 60% up time, is high problematic. Yes there are counter picks to Riven in lane, however, they do not nearly scale as well as her into the late game. Even if she is thoroughly shut down in lane, she can seek kills elsewhere, and by mid game is tearing through the rift dishing out significant AOE damage. These changes will tone her down slightly, easing laning against her and putting an end to AOE whole team executes if you're at 50% health.
