Tryndamere rework idea

Passive, Undying rage: Tryndamere gains rage from autos, spells, and taking damage. He gains 3% more rage for every 1% missing health FROM ENEMIES DAMAGING HIM. This means he does not gain bonus rage from his autos as he is low health. At 100 rage Tryndamere enters undying rage, making him immune to death from all sources of damage once activated for 2 seconds and does not burn any rage while in undying rage.

Q, Bloodlust: Passive: for every point of rage Tryndamere ignores 0.4% of the enemy's armor. Active: Tryndamere consumes 30 or 60 rage, depending on how full his rage meter is. At 30 rage his next auto will "crit" for 170% total AD. At 60 rage, the damage is increased to 230% and ignores all BONUS ARMOR.

W, Cowardice: Tryndamere passively gains 30-60% bonus movespeed toward fleeing enemy champions that he has damaged or been damaged by in the past 2 seconds. At 50 rage Tryndamere can activate his W to increase the movespeed by 50% and make his next auto cut their legs, slowing them by 80% which decays over 3 seconds. He loses his W passive while it is on CD.

E, Spinning Slash: Tryndamere spins toward a direction, stopping at the first enemy large monster, epic monster, scuttle crab, or champion hit. At 40 rage he does not stop and will inflict a bleed for 12% of the enemy's max health over 2 seconds as physical damage. No longer resets on crits or autos.

R, Eternal Rage: Tryndamere may only activate this move while in Undying Rage. Tryndamere refuses to die at all costs and from reaching his goal. Upon activation, Tryndamere removes Undying Rage, gains 100% of his rage, and his fury will be part of his new health, absorbing 0.4/0.7/1% of his max health as damage( if he has 3k health, at level 16 he essentially has 6k health if the enemy focuses him). Eternal Rage negates ALL HEALING EFFECTS ON TRYNDAMERE(Soraka, lifesteal, potions). Eternal rage lasts 7 seconds. He does not lose rage from his spells.

I rushed this idea a bit, numbers are probably too high and bonkers but leave me some feedback on what looks good as an ability, if undying and eternal rage seem redundant ill change them around.

FEEDBACK GREATLY APPRECIATED.
