But Riven does need a resource akin to Energy; one of my theories on the "Ragequit Riven" being so prevalent is her all-in kit without resources, making some fools mindlessly spam her abilities to steamroll the opponent and then wonder why they had a dog's death.

She could have her own resource, Ki, that acts like Energy and boosts Ki Blast.
