This *is* interesting for us boxers in wpvp. It pretty much swings the pendulum all the way back to non-tanks being the best when they're either backed by a healer or have their own healing mechanics.

Specifically, 40% damage reduction means non-tanks will be taking only a little more damage than a tank in wpvp, while doing perhaps two or three times the DPS. It also means healers gained not only 40% damage reduction, but they also 'gained' a 40% increase to their healing output relative to damage done.

I've had 4-5 teams on the sidelines that I refused to play on Argus because a Rogue with cloak/shoulders could bring them to ~20% in one global.
