Riot you need to choose between high mobility/low cooldown dash and scaling % true damage on Fiora.

She can't have both Riot because just one of those is extremely powerful let alone having both of them.

Seriously the whole reason she chokes out other top lanes is because she can both dance around them and out damage them while having insane dueling tools.

Honestly you could probably change that percent true damage to percent physical damage and she would probably be perfectly fine.
