So I'm looking harder at the guardian and reading about the threat techniques, ferocious vengeance and mitigated harm. It makes taunt more integral to the guardian, but ferocious vengeance is just objectively better than the other. Extra damage to EVERY strike against a taunted enemy that hit one of your comrades, but the mitigate harm technique only gives you damage resistance against CRITICAL hits against you by taunted enemies!? I know that taunt makes it easier to hit/crit you, but that means it still only works a tiny fraction of the time when You're going to be getting hit the hardest. I don't like this. At least make the effects even!! If one guardian gets a constant extra damage vs every strike, then the other should get constant resistance against every strike. I also think doing it this way opens up the idea of these being more important decisions for the guardian, and if you made them subclasses that worked like rogue rackets, you could make furious vengeance keep strength as it's key, but maybe give mitigate harm constitution as it's key. Letting players pick between being heavy hitters that are hard to hit, or tanky damage sponges.
