Riven Balance Idea
everybody hates riven mains, and it's easy to see why. riven is essentially a manaless kassadin who has an insane powerspike at level 2, ridiculous map mobility, and doesn't need boots. here's my suggestion for fixing her:
make riven an energy champion...
give her 250 energy, regenerating 8 energy per second, make all her abilities cost 40 energy each, and make it so that her passive restores 25 energy on hit. that way she only has insane mobility and stick potential while in combot, and can't just mindlessly spam her abilities to move across the map.
