Champion concept (looking for opinions)

Black belt, the fighting master (still thinking about a name) He would be a melee fighter, that could switch between 3 forms, each one sharing 1 similar abilities with another form, and each one having a different passive for his auto attacks.

Abilities:

R - Martial arts master: He can switch between 3 fighting styles (Karate, boxing and judo), each one has similar abilities, but with different effects and a different passive.

Boxing: Q - Uppercut: He punches his opponent using an uppercut, dealing X dmg and knocking up the enemy (small knock up) W (passive) - Boxing style: Auto attacks while using boxing style deal additional damage and cause enemies to bleed, dealing X dmg for 3 seconds. E - Counter punch: After activating this ability he will block the next basic attack, returning half of its damage plus X dmg

Karate: Q - Quick punch: He quickly punches his opponent twice, dealing X dmg each time (applies on hit effects) W- Jump kick: dashes a short distance, dealing X damage and stoping if he hits an enemy- E (passive) - Karate style: His auto attacks are kicks instead, gaining range (still melee)

Judo: Q (passive) - Judo style: His auto attack snare the enemies (cant happen more than once every X seconds). W- Somersault: Rolls a short distance, gaining X armor and magic resist during 5 seconds. E - counter attack: He blocks the next enemy auto attack, flinging that enemy to his back (doesn't return any damage).

Passive - Rest after a fight: His abilities have no cost, but give him 10 "breathless points". At 200 "breathless points", he gets silenced, slowed and cant auto attack during 3 seconds but heals for 5% of his total hp (and gets 0 "breathless points" again). Whenever he's out of combat for at least 3 seconds, he looses 5 points per second.

I used a "X" on the damage because i'm not sure which base damage and scaling i should use. What do you think about this champion concept? I'm not very good at drawing too, but i imagine him with a kimono or something, maybe he could change outfits depending on the fighting style he's using.
