I know my name is angryplateguy, but I'm honestly not that angry. I was just pointing out that, sure agility may not give you 100% dodge like back in BC with your double ZA daggers slotted with epic agility gems, where you can feel free to tank all raid bosses as a rogue, but it still gives you crit. It has since vanilla, crit and dodge.
Strength only recently, what back in cata right-?-, started giving parry. It's a decent amount, but it really feels more for the tanks than for pvp. If strength suddenly gave you 30% parry for having 16k, there would be an imbalance. Considering you don't get much more parry than a rogue gets dodge, and you ALSO do not get crit -or lets say for arguments sake haste or mastery or something ridiculous- it's not really a problem.
