Just a thought. Would be nice to see, for example, DD get +vit and/or toughness so they can run a more durable amulet, which would let anet adjust various other things about the spec (such as shifting durability a little bit, trimming evades for ex while still retaining overall brawliness).
Same for the others. Zerker got -toughness (for unfathomable reasons, but w/e) - it'd be fair to add some vit to the same trait. I still think scrapper's -300 vitality is horrendously stupid, but balancing it out with +300 toughness would be interesting
