Will this Q allow him reset his auto attacks? It would be nice to know. Also, if you want that 30% to be a base (and I believe it may be a good idea to have it also scale), then the description should say "His next attack deals bonus damage with a 30% additive increase in critical chance." I also think it's fine if the bonus damage scales a bit more up, at a 30/40/50/60/70 (+50% bonus AD)

When building a champion, not all of us can make it perfect. Other users have made that mistake, so you are not the only "offender".

It's nice to have a champion that can fulfill more than one role depending on their setup (some can even play outside their given roles, such as Sion as support; I've done that and it's not that bad). For this champion though...I would believe a Tanky Support would be better. You don't have to make him actual tanky, but a pseudo-tank who just takes hits but avoids damage (through barriers or invulnerability). Otherwise, just mess the idea a bit and make this champion yours.

As for the passive, as the one user mentioned above, the ability is still powerful. You did compensate his weakness when under 50%, but I think that only made his powerful ability a bit more powerful. I presume it may be better to have the following: "Alleron inflicts 0.15%/0.17%/0.19%/0.21%/0.23%/0.25% bonus damage to enemies for every 1% of current health above 20% of his max health. Alleron also receives 0.15%/0.17%/0.19%/0.21%/0.23%/0.25% bonus healing from outside sources for every 1% missing health when under 80% of his maximum health." This will allow the champion to have a balance when at certain points of his health; the absolute "when above/below 50%" can be a game changer or a plain game disruptor.

I would build Alleron somewhat hybrid in a couple of ways. Due to how he has high mana costs and a small mana pool, he'll need that. He boasts health, and his main passive will may benefit from it. As a secondary marksman, he'll need AD. His abilities also rely on AP, so why not that...yeah, Trinity Force would help the most, along with Athene's Unholy Grail to take care of his Mana problems.
