Square wants to remind us that the primary purpose of a tank is to...well, tank. Tanks were becoming melee dps with defensive cooldowns, and square wanted to fix that.

They're arrogant and think the only thing that matters is dps. So if a vitality accessory has parry, they won't wear it. Nothing matters except for their own parse numbers.

Good news is, we have crafted and midas and lore accessories now. If you really hate parry that much, there should be an option to avoid it among 3 sets.

They're forgetting that having extra hp has >0 value. Replacing parry on one accessory for a strength accessory with more desirable stats is a very marginal dps increase compared to the value of extra hp. If I save one heal due to the tank having deeper hp and can throw out one extra stone iii or broil once in a while, that's also an increase in dps. If a little extra hp saves dying even once, that more than makes up for the loss in one "bad" secondary stat.
