Tanks, please use strength gear.. :(

Vit doesn't increase dmg mitigation. 3K more Hp doesn't really make a difference (you just stay alive 2 more seconds in Hl content). If the full Str tank use his cd def correctly, the healer is suppose to be able to deal damage too.
Personnaly as an Astro i always prefered str Tank in my team just for the principe of optimization. And often there was bad str tank and bad vit tank. If the tank doesn't use his CDs, vit or str, we have to babysit him.

For starters, where are you getting this incorrect number? 3k hp? 2 seconds? You're wrong on both accounts.

Personally, full vit Sesh = 19,130 base (no party no food)/ Warrior would be 23,912 (taking into account Defiance, as it is the actual tank stance)
And then full str Sesh = 14,210 base (no party no food)/ Warrior would be 17,762 (taking into account Defiance, as it is the actual tank stance)

So right there, you undercut the total HP of what I would consider an average geared DRK/PLD by around 40% to fit your argument. Not to mention on warrior this total number of hp difference comes out to 6,150, more than double your estimates of how much additional HP a full vit has.

Now let's look at how long that would help someone live and assume your incorrect estimate of 2 seconds was accurate. Every boss/pack of mobs follows a set patern or rotation. During almost every single one of these patterns, the boss has short periods of time where he will focus on doing something other than damaging the tank, and the mob packs will stop to cast an easily avoidable-without-cooldown-management ability, during such time they are doing no real damage.

Now, let's say tank A (Str tank) dies near this point. tank B (vit tank) now has 2 seconds to live. However, if at any point in these "2 seconds" the group pack or boss mob hits one of these lulls in their tank damage rotation, you now have a 7+ second window to heal a low health tank, rather than revive a dead one.

In the future, please consider doing more than rolling your eyes and smashing your gorilla hands on the keyboard before formulating a response about something you put absolutely no FKNG thought into.

Oh and to answer anyone who asks, you're god damn right I'm mad. You LOSE! Good DAY sir!
