that sounds nice

A 10% less damage taken could definitely be a game changer on some encounter when you're low on gear.

However one problem remain, (beside a phase transition) there's no effective way to change pet.
So usually this would be something you decide to use on pull and as far as I'm concerned, most group would rather have Radiant Shield or Contagion over that.
The very short 60sec cd of Radiant and Contagion doesn't help as you can't just use them on pull and disregard the pet for the next 120 or 180sec.

On the other hand, I have the feeling that being able to to weave easily between pet would actually be problematic balance wise as you could apply Radiant Shield, Contagion and Titan's Heart in succession.


While I love the idea and it's definitely something that would make Titan usable in a raid scenario, beside world first struggling to survive concecutive AoE burst at specific time, I don't see this being of much use overall.
