I have an idea on reworking Tryndamere into a Bruiser rather than a melee ADC

I was discussing with a friend of mine and we thought that Tryndamere should be a Bruiser who is hard to kill, and takes another extra push to kill when he has barely any health, and not some RNG reliant, split pushing abomination that can't be buffed today.

Passive: It is the same except he no longer gains crit chance with more fury, instead he gains AD with more fury, gaining 10 AD at max fury at level 1, and 60-80 AD at max fury at level 18.

Q Passive: The same mechanic except it doesn't give him AD anymore, he instead gains health regen based on his missing health. At level 1 of his Q he would restore 3% missing health every 5 seconds, and at rank 5 he would restore 15% missing health every 5 seconds. The lower health he has, the more the regen increases. At level 1 he would restore 15% missing health every 5 seconds when below 10% health, and at level 5 of his Q he would restore 40% of his missing health every 5 seconds when below 10% health.

Q Active: He consumes his fury in order to heal himself right away. The heal doesn't heal for a flat amount anymore+fury, it instead heals for his max health+fury.

At level 1 Q with 0 fury, he would restore 3% of his max health. At level 1 Q with full fury, he would restore 15% of his max health.

At level 5 Q with 0 fury, he would restore 5% of his max health. At level 5 Q with full fury, he would restore 25% of his max health.

My thought process was that he should be a barbarian who will try to go all in on you, and if he's playing defensively, he loses his damage steroid in order to heal himself so that he can keep on fighting you.

New W: Kings Shout: Tryndamere lets out a battle cry, decreasing all damage to him by 10-20% for 5 seconds. Enemies with their back to Tryndamere lose movespeed as they are cowardly to the king. This basically is the same as his current W except now it doesn't make them lose 80 AD with his high skill cap W button.

E: Spinning Slash: This is basically the same skill as current Tryndamere on live except now it loses its AP Ratio in exchange for a better AD scaling along with a more reliable reset mechanic. His E loses 1 second of its cooldown for every 2 auto attacks Tryndamere does.

R: Undying Rage Tryndamere refuses to die for 5 seconds, this is the same on live.

tl:dr Tryndamere should be more of a Bruiser who is hard to kill and requires an extra push to kill when he has no health. Tryndamere can basically still do what he normally does and dive in with 0 shits given except now he can't crit somebody 2 times, kill them, then escape with his ult, he will actually need his team to do most of the damage and he will keep jumping in to kill/distract the enemy ADC.
