Thanks for this detailed review.

Firstly, the Blue Form has implicit inconvenients: spells pass through anything, but each enemy hit will raise his fury, making him soon unable to cast more spells until be switches to Green Form. Since Ahri already deals true damage scaling with AP, I thought it should be OK to make other spells dealing scaling true damage too (even if the scalings are pretty bad). For a whole cycle of spells (considering they only hit one target, which is difficult in lanes because of minions), Elmye will gain 60 fury, meaning Barrier would be his last spell in the current form or he can cast 4 more times Ethereal Sword or Psychic Chain. But here's a little twist: Elmye only spends 80 fury by using Form Shift, meaning he can get Blue Form starting with 0 to 20 fury left. At this point, he can cast a whole cycle to unlock the spell again, but the other twist is that he can't just line up Form Shift one after the other: his cooldown is also a limit. If he reaches 100 fury and Form Shift is on cooldown, he has no solution left but use auto-attacks.

Before reaching the Blue Form, he has to build up enough fury in Green Form and in Red Form. Getting rid of each one has a difficulty and something to make it easy if you go full AP. Green Form needs a target to hit, otherwise the spell won't be used. However, if you play AP that's not a big problem since you'll still deal damage. Red Form uses AD, making you weak from dealing poor damage, as you have to wait until Form Shift's cooldown is over. At the opposite of the Green Form, this one lets you throw your skillshots anywhere to get enough fury to reach the Blue Form.

Now about your idea for the blue passive: I consider the whole passive as a way to stay a little more efficient even if you reached 100 fury and can't switch form yet, that makes every auto-attack a micro-spell. Making the blue passive deal flat bonus true damage would be either too strong in laning phase, too weak during teamfights, or both. It's all about the moment where you're optimizing the flat bonus damage. The general idea of the form itself is making the champion create bodiless weapons that hurt without injuring his target, like activating the nerves that transmit pain while his creations pass through his targets, inflicting pain you can't protect yourself from. Making the passive deal physical damage would not match what he actually does.

Elmye really can't just stick to one form without having to put up with the other 2, the whole R spell's purpose is to prevent this by forcing the player to change often. His other spells come back quickly, however it wouldn't be wise to spam them. If this champion has a visual indication that Form Shift is on cooldown, his enemies can look at his appearance and his fury bar in order to pick the right moment to attack.
