When I posted my reply that didn't have quotes, I didn't quote anything because you only wrote a single paragraph. After refreshing the page, two more quotes popped up and I didn't reply to those until my next post.
Except in this game, the terms raid and dungeon are used to differentiate between 8 man content and 4 man content. We don't say dungeon and expect someone to correlate that with 8 man content. 8 man content is trial / raid content. 4 man content will not teach a tank how to OT nor will it teach a tank how to tank swap correctly. We are all familiar with those Defiance / Grit / ShO OTs in 24-man content that didn't know better. That's what happens when you don't teach someone how to raid.
No, I would still use my CDs as there is nothing else to use them on for one CD cycle. That's what I mean when I say you have a surplus of mitigation. Saving it wouldn't do anything but be a complete waste. I know this because I push my DPS and doing so requires that I know exactly when I will have my CDs.
It doesn't matter that you need more healing because that's what they're doing anyways. Healing. Regardless of if you're in tank stance or not, they can't afford to not top you off because the TB hits hard and hits often. Even if it takes them another cast of healing, they're not losing the opportunity to Cleric Stance and DPS.
And...
...right on queue. Yoshida just flat out said that it was by their design that ACC works the way it does. How is that a player driven meta? He flat out says that they tuned content so early clear groups have no choice but to stack ACC to push DPS. It's convenient you just completely deleted that part, huh?
My god... LOL. You do realize that you began this argument by saying that tanks needed to change because some random PLD got carried through A11N while only spamming RoH and you didn't think it was right the content didn't have a hard tank check to gate him until he learned how to play by your standards.
Ridiculous.
