Self-commenting makes you sound a bit self-centered, but hey. You've got someone.

My points:
 * This passive is unique to say the least. But the fact that we don't know how spores are spawned and how many petals you get to stock with each spell is a little imprecision that could massively change the power of the character.
 * The Q has weak base damage, but adding damage to each petal kinda sounds overboard with that AP scaling. How long does the mark even last anyway?
 * This W, I'm not sure Rito would like this. Mana sustain is not something that Rito puts in champions' kits; the latest source of it I remember was Soraka's old click-shot silence that could refund mana to allies. Also, the free instant root upon being attacked on top of that, I absolutely hate this. This would make her a completely oppressive support: E your ADC, let them get hit once and root the enemy ADC, then pick the poor sap off for free.
 * This E. Please: 300 base damage and the guarantee to also hit champs on Naut's Q while knocking back minions on your way, sounds harsh. Add a 2-second disarm effect and yeah, when I say this champion is looking OP for a support, just look at the utility.
 * Err... 1-second CD on this ult means free passive procs. Add to that a heal every 50 seconds (27.5 secs on a 45% CDR). The fact that the shot cannot kill though... might not be compensation for the fact that with three stacks at the beginning of a teamfight, you can land 1200 damage and on top of that. Hitting 6 basically makes this champ a burst mage who simply needs to recharge this massive FU-Shot.

TL;DR: The interactions between the abilities are pretty interesting, just... too strong.
