Eternal Guard overpowered?

[wobbly]

With a high-range shield with a lot of resists (or combined with spectral shield) your carving off 300 or more points of damage on every single damage source. This meant 90% of the voratun armoury's main room wasn't scratching me.

I tested it in the voratun vault by standing in the middle with true-grit on & a talent lvl 1 anti-magic shield+resolve & a shield with 173 block in all the elemental resists. Just block+regen+heroism+a heal. They eventually killed me, by disarming me but not before they were down to the last 2 overpowered greater multi-hued wyrms. A disarm-immune bulwark with eternal guard could probably clear that room just standing in the center blocking & regenerating till the smoke cleared.
