While tank design is a large part of the problem, I don't agree that they need their HP increased or self mitigation reduced. It's the healing that needs to be removed from their job design. Their current mitigation alone wouldn't save them except in short fights. HP attrition would lead to their death after a couple of minutes. Currently they can survive near indefinitely without a healer because of the generous amount of self-healing they can do.

It's the self healing that needs to go. That at least would give healers more healing to do since SE seems to be too scared to increase party-wide damage.

Take the extra step to add in more party wide damage as well and healers would be that much happier. As you say it doesn't need to be a huge amount that would make healers feel pressured but there needs to be more for healers to heal than the current DPS mistakes and infrequent party wide tickles. Making the damage received from mechanics more impactful would also force DPS to take the mechanics more seriously instead of just standing in them because "healer's got me covered once I hit 4 vuln stacks".

I enjoy healing so I play healer.

That doesn't mean I don't feel there are some pretty obvious problems with how healers fit into the game's battle design and wish SE would address them.

I may not agree with most of what the OP has suggested as being the solution but I'm not going to make snarky assumptions about them like you did.
