I honestly prefer the DPS focus of the current meta. I imagine there's quite a few tanks that feel the same, and I'd wager its partly why we have as many tanks as we do now. The amount of people willing/wanting to do meat wall tanking is small and always has been historically in most MMOs. Its why even today when you pull up the roulettes they're always looking for Tanks more often than not.
It's also not like it's a new thing to FFXIV. Pretty much every single MMO in general has had tanks get enough survivability and then shift everything into DPS. The difference here is that base stat levels are high enough that we're already to the point of going full DPS.
