Need a boxer champion!! "Marcus, the Contendor"

Why has there not been a boxer champion?! I think he would be a spectacular addition to the selection of champions! He would be a Fighter/tank type champion being exceptionally good against other melee champions, but vulnerable to ranged due to the fact he needs to be toe to toe to duke it out with those unfortunate to stand in front of him! He will be an energy based champion sort of like Lee Sin. He is to be built tanky for he needs to be alive to perform his complex combinations which can still dish out devastating damage to begin with.

Stoneface(Passive): Marcus is so tough in the ring he is immune to any crowd control that stuns, but can still suffer damage from the spell.

Left Hook/Right Hook: Click continuously to make Marcus swing one fist after the other. If landed 3 times target is stunned for .5 seconds.

Cutting the Corner: While attacking an enemy champion, Marcus slightly moves around target, good for avoiding any enemies trying to skill shot close range. Also if landing a left or right hook directly after activating Pivot, target is knocked slightly into that direction.

Defense/Counter: Marcus can rope-a-dope enemies! When defense is activated Marcus will raise his guard up and bob and weave to reduce incoming damage as well as slow enemies attack speed, and when he is attacked he can activate Counter and quickly jab twice (but does damage as if it were 1 attack) whoever is attacking him every 2.5 seconds dealing increased damage the more he Counters.

Flourish/Haymaker (Ultimate): Marcus activates this and his attacks turn into devastating/quick combos which slow enemies movement speed by using his enemies heads' as speedbags!. He can activate this again to Haymaker instead, attacking at normal speed but throwing devastating blows which has a chance to knock back and stun for a short duration.
