Champion Concept -- The Dragon Knight

So League of Legends has Shyvana, a Champion that has the soul of a Dragon and can transform into one, Aurelion Sol who IS a Dragon and they have also Dabbled in some Dragon Trainer Skins but what about an ACTUAL dragon trainer/rider/knight? Someone who has a ethereal connection to a dragon and can draw strength from it.

The Dragon knight is a Top lane Juggernaut who fights with the same ferocity of a dragon and eventually fights alongside one.

Now keep in mind, I started writing this when it was just a thought in my head so actual numbers, scaling and mechanics are a little non existent at the moment.

P Ferocious - The Dragon knight fights as ruthlessly as his mount and Surrender is never an option, granting him 1% bonus Attack Damage for every 3% missing health. (I know Olaf has a 1-1 ratio with Attack speed, but i feel like a 1-1 ratio on attack damage would be super busted. Like one shoting their ADC because you have 3 health and you flash q..and like i said, I have no clue how these numbers would actually preform, they are just here to give an idea of the champion.)

Q Tooth And Nail -- The Dragon knight Calls upon his Dragon counterpart to infuse his sword with the tooth and nail power of the magnificent beast. His next 4 Auto Attacks Deal bonus physical damage and grant him some Lethatity.

W Winged Slash -- The Dragon knight's companion grants him the gift of flight, allowing him to dash a moderate distance and slightly knock back/up enemies. (think Riven's 3rd Q only longer distance to dash)

E Airstrike -- The Dragon Knight channels for a short duration, marking a short strip of the ground (about as big as a Corki Valkarie) for his Winged companion to rain down fire. (A mini Rumble Equalizer).

R UNITE! -- The Dragon Knight channels for a period of time, calling down his monstrous mount. The Dragon is a pet like Daisy and Tibbers but what makes the Dragon knight's pet unique is the option to mount and dismount his Fearsome friend. When Mounted, the Dragon and his rider are grounded, having increased "Tank" Stats like Health/Armor/Magic resist at the drawback of movement speed and potential damage output. The Dragon knight can still use his other abilities, which are amplified due to the very close proximity of his Draconic Spirit Brother. When Dismounted, The Dragon takes Flight, Removing bonus resistances from both the Champion and The Dragon, but in turn Granting the Dragon extra movement speed, allowing it to ignore unit collision, and giving it bonus attack range. (shoot fireballs instead of slashing with its claws.) This Ult Would be on a longer cool down than most other Champion Ultimates as It does have more utility. I Picture almost like switching between something resembling a mega gnar and something like Reworked Yorick's Ultimate.

This concept is one that I've always enjoyed (I build this Character in most video games that entertain the concept; as well as pen and paper games like Dungeons and Dragons) and would like to see it hit the rift at some point in my League of Legends Career, but as expected, Riot has TONS of champion reworks as well as champion releases in their schedule. This concept would also take A LOT of balancing and tampering around with in regards of using different abilities and all around changing up his kit. After all he does just seem like a modge podge of Kleds W, Riven's Q, Rumbles R but downsized, and an interesting take on a pet style Ult. Who knows, Maybe they can make it work...
