Here's how to fix TBN

[RyuDragnier]

Increasing 5% TBN after Shadowbringer won't ever be used, and adding more % will only lead to another issue, TBN negating mechanics.

Not that I don't agree with you, but I have to remind you...they can code things to always apply, regardless of whether all the damage is blocked or not.

The key to fixing TBN is to remove Living Dead from the game.

True, but we also need to remember TBN scaling is a lot stronger than Sheltron/HoC/BW vs Busters/Power Hits, the ability can soak a buster by it's self with more HP added up. I know TBN isn't massive value vs mass targets, but Savage/Ultimate tiers it's far above them, other tanks need to respond with another strong cooldown on top, Drk can throw a cheap Dark Mind, or Rampart, then call "tis but a scratch" - Black Knight. Increasing TBN % removes need of Dark Mind/Rampart, and use Rampart/Shadowall/Dark Mind in other places, making Drk more impenetrable vs other tanks. Increase the busters? Pld/War get lead into mitigation problems. Balance is annoying system.

It would be much more useful in dungeon pulls if TBN had actually no cooldown tied to it.

It would be broken af if it had no cooldown. You'd just keep chaining it until you're down to 2 mobs left or run out of MP. During burst, especially due to Quietus's 500 MP per hit under Delirium, you could churn out a good 5 TBNs nearly back-to-back, for up to some 20+ seconds of near invulnerability. Let's rein Warrior in just a little, not just try to put a new broken tank at the top.

Like using shadowbringer will increase the effect of tbn by 5% per use.

Shadowbringer is never going to be used outside of raid buffs. There's just not enough damage against tanks to justify losing 60+ potency just to add another ~64 potency (5% of its current value, at rough Vitality->potency parity) to TBN's shield. At most, it'd make TBN slightly less freely weaveable for the next use after raid buffs since it'd have an extra 20% required damage to refund itself. It won't save a healer GCD, nor a life, but it could cost you an Edge/Flood.
