Riven
After playing with riven for a while I have noticed her shield has become a fancy animation/slight movement instead of what it is intended to be. The amount of damage it can absorb is not the problem, it is the time period in which the shield is active. The shield is meant to be a small gap closer/attacking ability but instead has become only a very small gap closer in which the enemy has the opertunity to hurt in simple by waiting the short time in which it takes for the shield to fade. I believe the shield should be returned to its original time period or start at its current time and grow along with her when the player levels the skill up.
