A possible Idea for a Tryndamere Ult Rework

Recently, a friend and I played a game against a Tryndamere and were very frustrated by how he could just press R and kill everyone. So as opposed to him saying "DELETE TRYNDAMERE FOR FUCKS SAKE!!!!" I said, why not rework it to keep the identity but not keep it as toxic as it currently is. My idea when Tryndamere activates his ultimate, he gets a buff that upon taking fatal damage, the damage is negated and a portion of the damage is healed. This would allow him to still have the "I'M NOT DIEING NOW" identity while still allowing him to be focused down if the enemy decides to. Upvote and tell me what you guys thing. Crossing my fingers for some Reds to see this.
