Riven is a bit more of a bruiser than an out-and-out skirmisher, seeing as I see at least half-tank builds on her. Also, her aoes are not really big.

"How can you swing your sword and damage only 1 enemy?", you say? Just ask every champion in the game with a horizontal swing autoattack animation. comes to my mind.

"He is the crazy dude that dashes around, swing his sword and cause Chaos." Finally, some semblance of a niche. Though I'm sure you can pick just about any other champion with a sword and tons of dashes, and by that I mean.

You need to use energy restore more often, but unless you have your E (a one-point wonder as far as energy restoration is concerned), you have no energy restoration mechanic whatsoever. "Early game he got even higher costs as restriction of his power and reduce his pressure over his opponents.", but actually you just have to proc your E energy restores. Also, that combo I mentioned earlier? Once you're done with it, you have 60 energy, so you only have to wait out the cooldown on E after that empowered cast, which is around 4 seconds, but by that time, you'll have restored like 40 energy. With 100 energy, you're close enough to a double-cast into energy restore that'll give you 60 energy again.

Sustain based on how low your health is makes me think of, who becomes damn near unkillable due to his W lifesteal and his passive attack speed. Except this here dude's heal (and bonus true damage) comes in massive bursts instead of gradually.

Yasuo and Riven's dashes are actually gated by minor mechanics, Riven less so than Yasuo. Yasuo's "dash resource" is something that cannot be grinded for, on top of that, since it's enemy units.
