Yes, only because tank stance lost its damage penalty. Therefore, it's no longer a near 50% damage loss to sit in tank stance because the DPS are too lazy to press a oGCD that doesn't impact their rotation one bit. If you can't be bothered to press Diversion, why should I bother saving you from the tank buster?
"Because it's your job!" Except you're interrupting my playstyle~
Okay. Friends and I did Ghimlyt Dark without a healer. I still did every mass pull and spot healed with Steel Cyclone. Expert dungeons are so pitifully weak, a non-DPSing healer is actually useless.
You do realize this makes tanks even more glorified DPS who only pop CDs when a buster comes out, yes? While I do think the mitigation tools available has become excessive. Taking them away entirely dumbs down tank gameplay. The better solution is to increase outgoing damage and/or nerf healing potencies. You achieve the same results without neutering tank responsibility to accomplish it.
Translation: Tanks and healers can be lazy while DPS have to utilize their full kits. As we established, Expert dungeons hit like wet noodles. Why do healers have an excuse to AFK and watch Netflix yet if I only pressed 123 on Dragoon, I'd be called out for it?
"But it's your job to do damage!" And it's your job to benefit the party in whatever manner you can, either through healing or damage. If you get to only utilize half your kit, I'll do the same.
What the OP—in a two year old thread that is ironically quite relevant—has shown is responsible for an efficient run of any content falls onto everyone. And no one person should think themselves above another that they can skate by half-asking it. I am not going to spend an extra 10+ minutes in a dungeon because you want to watch Netflix or Youtube. How is that in any way considerate?
Except we aren't talking about bad tanks who have no idea how to play their job. Unless they are extremely undergeared, aggro won't be an issue for a decent tank... provided the DPS press an ability which does not impact their rotation whatsoever. Why should I spam Butcher's Block or Power Slash several times because Mr. Samurai can't be bothered to hit Diversion? More often than not, I'll be either riding very closely to said Samurai's damage or outright surpassing it.
Fortunately, this is a non-issue now since tank stance has no penalty and aggro management is basically nonexistent.
