I like how Kai'sa is so simple, but I feel like she lacks satisfying abilities.

Passive: On hit damage, evolve with items. Q: short burst of DPS. AD for more damage. W: Skillshot nuke, long range. AP for more damage. E: Speed boost into AS steroid. AS for an invis. R: Dash near a guy you've hit.

She's simple, yeah, but she doesn't give you the same cathartic satisfaction as somebody like Garen, Tristana, or Vlad.

She gives me Kindred vibes. She's an agile, gank-centered marksman with part of her kit locked behind a kind of gimmick. Her abilities are simple, but most of them seem a bit formulaic. Her visuals are solid (though her thematic execution remains to be seen) but her gameplay seems like it could be iffy.

Her kit has the potential to do work, but she's heavily reliant on her numbers being high. If her numbers aren't good, the champion itself can't be.
