Endurance...
I’ve been talking about this idea since I heard WP mention it in one of his videos a few weeks back.
I would rather use Vitality to scale endurance regen, because I feel like Toughness should be used to address the Defiant mechanic. If they made it so that you can strip 3-5 stacks of Defiant at 2500 toughness, you could truly perform the “control” role Anet talked about before launch. 2500 Toughness is not 2500 armor. Check a gw2 build editor to see just how hard it is to reach 2500 toughness. This would be a specifically non-zerker build that can effectively reduce a boss’s DPS, and thus the longevity of the party. You would be tanky and deal low damage, but you could still help the party immensely.
That’s an interesting idea. I don’t really see the connection between toughness and defiance, but the concept of being able to remove multiple stacks of interesting.
