Generally speaking it seems like very few people build for a tank. I've seen about 2.5 that worked.

Won't the new Bulwark mode present a huge problem? If you deal half damage you will never keep aggro because about 90% of the other people I met run full dps builds.

It doesn't really seem worthwhile to use considering the best defense from dying in combat is to just use a run skill and make the monster take 20 seconds to chase you. For solo play it also makes zero sense to take -27% damage but deal -50% damage.

Overall 13 armor regeneration is fantastic - when you are fighting level 20 mobs. When monsters can deal 600+ armor in one hit it doesn't matter that you got 13 back.

*suggestion* : change the new skill to make the ratio more like : -27 incoming, -35 outgoing.

If you change the power ratio so that full power skills are dealing half damage the net result with the current changes is :

1. I do half damage but take about 25% less damage.
2. I get a miniscule bit of armor back
3. I get a little bit of power back (shaman infusion provides more)

These three together should offer the player a net gain but what you have offered currently is a net loss. The only time the new ability sounds worth using to me is to make content way below my level deal zero damage thanks to the new 27% modifier. The only problem with that idea is I already have a build that does that with full damage.
