I'm not sure what your group is doing because mine doesn't have those problems. It seems this thread is divided between people who have a ton of problems and people who don't. Since it's unlikely that some of us have unfair advantages in the game (free cures, 10,000 MP, etc.) I can only assume that the side having issues is doing something wrong.

I suppose you could just stop and regain your MP before pressing forward if a lack of mana is that huge a problem for you.

What I can say is prior to 1.18 I used to watch television while doing leves and would simply spam AoE cure III, all the while barely looking at my PC monitor and could do this pretty much indefinitely until the leve ended. That to me seems more broken than having to be efficient with your mana.

The fact is people have completed this dungeon, using the same mechanics you have. People who have not are progressing further and further in it every day... again... using the same mechanic you have. If your problem is tanks not being able to hold hate, discuss with your group how you can better control enmity. If your problem is a lack of MP, discuss with your group how you can be more efficient. Adapt. Evolve. Progress.

I can't help but think this has more to do with this being more or less the only real content in the game so far. Maybe try the R25 dungeon? It just sounds like people want everything nerfed JUST to the point that they themselves can complete it and complete it immediately... and where does that end? There's always going to be someone worse at the game than you and following this line of thinking we end right back where we started with a game that plays itself. Thanks but no thanks.

I suspect once the game is opened up a little more and there's various things to do for a wide range of skilled and not-so-skilled players, people will be less worried about what someone else is able to do and they're not.
Had 100% of the FFXIV community downed Batraal the first night of 1.18 we would all be here rightly claiming FFXIV is dead and that Yoshi P's vision was a complete failure.
