From one tank to other tanks..STR Gear is not a thing anymore..Get used to it now!

To put it simply, you take the same damage with 10k or 100k HP. If you can survive a hit with 10k HP, why would you need 100k HP for it, especially if it significally lowers your damage? Extra HP in this case is wasted, but extra party damage is always useful.

This is a dangerous line of thought. Instead of thinking of health as raw numbers, instead think of it as a percentage. The difference between a boss dealing 90-110% of a tank's HP and 70-90% of a tank's HP is literally the difference of hours of practice time.
