I wouldn’t go that far in the comparison, but I agree with the general gist of it.
Especially in the current model, where it’s SO MUCH EASIER to get 475 (or the equivalent in the patch) from PvE (especially in M+) than it is to play at a rating that would earn that naturally in PvP.
Though on a slight tangent, M+ gearing has completely killed WoW gearing for the mid/low end with it rendering anything under Heroic Gear essentially unusable.
