Sorry, but no tank should pure vit stack right side.

Do we really have another thread about this? There's like 8 of them now.

You should equip whatever will facilitate the maximum performance on your part and the rest of the raid. If you have healers that are extremely good at DPSing, a few extra vit pieces may benefit the party. If your healers prefer to stick to healing more often than not, you should put on a bit more str. But pentamelds are still the best, which is a design flaw in and of itself. TL;DR You rolled tank, you need to be adaptable.

It is however, a logical fallacy, to assume that a tank wearing tank gear as opposed to DPS gear means they don't know how to play their job. There are as much newb, scrub tanks out there in full STR b/c they wanna be Xeno, as there are silly tanks in straight VIT that don't know how to manage their job/rotation/utilities any better.

It really only is a point of contention in raids. In casual/midcore content all a VIT tank means, assuming they are good at playing their job (there is nothing skill-based about swapping gearsets), is that a healer should be in Cleric Stance 50-75% of the time Baning DoTs or engaging in copious Holy/Gravity spam.
