I honestly think that PI with a substantially longer confession duration would be too powerful. Whilst it's kind of meh in casual gameplay, it's a great ability in Savage pretty much anytime the AoEs start coming in. It's massive reach is also something that's frequently overlooked.

15 seconds might work ok, but 20 or 30 seconds runs the risk of us being able to keep stacks rolling indefinitely in more challenging content which will just break it.
