Strength Tanks and You.

[Arrak]

A strength tank in dungeons won't be a problem if he uses his CD and don't pull all the mobs at a time. More HP won't usually help you survive on trash mobs and easy boss, it's on big boss like EX primals and Alexander where you need HP to survive big hits that it will matter, not on continuous hits.

This is actually the exact opposite for me. I VIT set for trash pulls so I can pull more mobs comfortably, then switch to STR for the bosses. STR Bismark, STR Ravana unless I'm solo tanking. The worst thing a tank can do is have only one gear set. Put the sets on your bar, know your group and fight, and be ready to switch to what best fits the situation.

This.

And most of the 50 Dungeons, especially as PLD, on bosses it isn't an issue to switch to sword oath and use CDs to mitigate. Albeit, I pretty only do that when the healer is obviously competent, or I go with a friend who is healer.

Those who don't use defensive cooldowns when needed in STR aren't going to magically start to use them in Vit either.

Healers also need to be aware of when tank busters are coming, not just the tank to pop a CD, but the healer to start precasting a heal ready for after the hit lands so the heal lands faster, fights are scripted. Bosses always do X after Y.
