How would you *fix* battle content?

[...]so be humble try playing a tank for one whole week i promise you will change your thinking right away an will be thankful the healer was at least "just there" to assist an make things a little easier an smoother even if they nose dived at the end you are not mad at them just glad they stuck it out long enough to reach the end period.

Been playing all 4 tanks in daily roulettes for years solely to get the 700/900 credits achievements without spamming o3n PFs - yeah no. I don't think it's a mad notion to wanting most of the HPS requirement being handled by the healer. Not the dps. And certainly not the tanks. But in good amount of my dungeon runs, that's just not the case. Sure, encounter design also affects this, but they're not mutually exclusive. Trying to pretend tanks' sustenance in their kits not being bloated is comical at this point. I should not be able to solo/duo bosses from <=65% even as a Dark Knight without the healer, or straight up replace them because it's more optimal to bring 3rd DPS.

If people were to ask for my opinion, NONE of the self sustains they've gained since the start of 6.0 were 'needed' at all. Warrior's SIO regen? RI/NF/BW change? Equilibrium HoT? Damnation HoT? No, they're all excessive. Paladin's HS regen? Intervention regen? maybe even their built in heals from their spells? No, they don't need those all. Gunbreaker's Aurora charges and buff? HoC heal? Pfftt not even close. Dark Knight was 'the best' imho until they somehow decides to buff Abyssal Drain. Great, yet another benediction at 1 minute cooldown has joined the tank's arsenal.

EDIT: there's also what I'd call the unforeseen collateral damage that they've created by letting tanks handle this much amount of required HPS for so long - is the healer would just phase out & conditioned to not actually heal when they needed to. I don't think that's a sentiment you'd like to foster.
