I like the changes to damage taken by pets (crit resistance and less damage from DOT and AOE so they don't die easily from collateral damage). But pets, especially sorc pets like twilight, still have low resistances, HP and they do NOT scale off the caster's CP, meaning they take a lot more damage in CP environments. Pets are really squishy in pvp and takes no effort to kill for someone deciding to focus it.
Can I suggest having pets scale off the casters' physical and spell resistances, as well as the casters' CP mitigations? Mitigation like block, guard and minor/major protection applied to the caster doesn't have to benefit the pet, just the casters' resistances and CP mitigation.
