Why does Clemency get interrupted? And why does Sword/Shield Oath reset combo?

[Launched]

This is not accurate. Increase in effective health... maybe (though not exactly. It's more like increase in Hp Mitigated. Effective Hp would also include expendable HP. A Pld gets 0 additional eHP from switching Oaths), but even if you consider Shield Oath a increase in effective health it is most certainly not an increase in effective healing.

You don't have a clue how tank stances or eHP works. Every bit of mitigation you get effectively increases your HP, whether it's 20% reduced damage from Rampart or 25% increased HP from Defiance. A PLD with 16k HP and Shield Oath effectively has 25% more HP: 20k eHP. And no, WAR doesn't have an easier time getting healed. Defiance only increases healing by 20% while HP is increased by 25%, so WARs actually recover LESS of their eHP from every single heal compared to PLD. And there's also the fact that abilities like Tetra and Lustrate aren't affected by Defiance at all.

Yes, it is truly terrible that Warrior Tanks need to actually tank sometimes instead of pretending to be Dps. It's so sad for them. How very inconsiderate of the Dev team.

Where did I say I was complaining about tanking? I like tanking as WAR. I'm pointing out that swapping to Defiance has its own disadvantages, which many PLDs/DRKs don't seem to realise.
