New Champion Concept, Dual Wielder

Hello forums! This is my first time posting on the league forums as I don't use them much. I am a gold 5 top lane Jax main. I just had this idea for a champion that was very basic at first, but then I started to flesh it out and crunch some numbers. I designed them to be a toplaner/jungler as those are my main positions ;). Sorry for the immense amount of typos as I typed this in a short amount of time and did not have much time to look back over it. Please give me some feed back on this champion as well as any balance changes. Thanks :D!

Concept Champion(Name Undecided) Just a brief introduction: The champion would wield 1 sword and no offhand weapon by default. When the ultimate is activated the champion dual wields two swords, one in each hand, augmenting their abilities. This champion is designed to be a top laner and possibly a jungler focused more on dealing damage than on tank stats. They have no resource, meaning the only thing stopping them from using an ability is its cooldown.

Passive: Swordplay No Cooldown Every third consecutive basic attack or ability deals additional physical damage scaling with attack damage and granting a small movement speed bonus.

Dual Wielding: Additionally, every third strike applies on-hit effects twice

“Q”: Fleet of Foot 12/11/10/9/8 Second Cooldown Dash to a target area. If an enemy champion is in a small radius around the target point, dashing to them instead dealing physical damage scaling with attack damage. If multiple enemies are in the hit circle, strike the one closest to the center. On Champion kill or assist, reset the cooldown of Fleet of Foot.

Dual Wielding: While dashing, strike with both swords in a circle around you dealing the damage of Fleet of Foot to all enemy champions in the hit circle instead of just one.

“W”: Riposte(Passive) 10/9/8/7/6 Second Cooldown 10/15/20/25/30% chance to reflect an incoming attack dealing damage and stunning the target. This ability has a brief internal cooldown of 10/9/8/7/6 seconds between dodges.(Damage is calculated as .5 of your attack damage and .5 of the incoming damage calculated before resistances)

Dual Wielding: Reflecting an attack not only stuns, but grants a small attack speed buff equal to 2/4/8/12/16% based on the number of skill points allocated to this ability.

“E”: Combo Sequence 35/30/25/20/15 Every attack consecutive attack after activation within a time window of two seconds adds a combo stack. Upon reactivation all stacks are consumed dealing physical damage. Each additional stack increases damage exponentially upon reactivation.

Dual Wielding: Apply two combo stacks with each basic attack and ability instead of one.

“R”: Twin Disciplines 75/60/45 Summon another magical sword to use in your offhand for a duration of 15 seconds. Passively gain attack speed equal to 30/45/60% respectively. Having an additional sword boosts your attack damage and attack speed by 25% as well as augmenting your other abilities. Scoring a kill or assist while Twin Disciplines is active extends the duration by 8 seconds.
