Lets stop fighting SE and work with them. What are your ideas?

1. Most mobs and bosses simply do too little single target damage overall to be a threat to us.
2. Healers have too much single target hps.
3. Tanks have too much hp.
4. Tanks have too much passive damage mitigation.

Personally, I think that there's an even bigger reason for the current meta, above everything you mention : Content is too predictable.
Back in 2.55, I'm pretty sure that if you added a random part in Titan Hard Mode, even top ilvl gear wouldn't allowed lots of people to clear it. It's also because of that that tanks can pinpoint how much of a safety net they need for each content.

So, first solution, make less scripted content. Bosses can have several abilities each with their own cooldown, and could use any ability from their list that isn't on CD. Second solution, make bosses react to what the players do instead of having time or HP trigger. For example, taking a sudden burst of damage could force (Or prevent) the boss to use a specific ability.

Nope, can't agree. I enjoy the current XIV meta for what it is

SE clearly show they want that Meta to die. The question is : Will you adapt or will you quit ?

The reason that some tanks are comfortable "ignoring their main stat" as you say is because HP is not our main stat, any more than MP is a healer's main stat.

VIT is our main stat since it's the only type of accessories we can need on, and eventually wear. The fact that it's not our damaging stat is irrelevant. And, by the way, Piety is not a main stat anymore, so you can't make that comparison.
