It's pretty simple honestly. Abiding by the game's current design philosophy for 99% of content. If the DPS or healer want to pull the 'mostly harmless' trash mobs, then I'll go in and grab aggro -regardless of the tanking role- with the same-y AoE single or rotation that every tanking job role has. I'm there to get a dungeon out of the way, not spend time deliberating on the ethics of who pulls what, in a game that isn't designed to penalise players for pulling ahead of the tank. The game itself, outside of very specific content, does not encourage a practised approach to pulling or aggro management. Turn on aggro mode. Spam AoE. Spam defensive CDs... .. at some point they're maybe needed?

Now. If the game was designed so that the DPS/Healer would get absolutely murdered for pulling ahead of me, that's another story. That's very much a teaching moment. One where I don't even have to get involved. Mobs that can pose a threat mean two things. It means that the tank is going to learn very quickly that they -need- that aggro, and it means that the DPS/Healer should learn very quickly that they absolutely -DO NOT- want that aggro.

In the past, I've had anxiety about tanking and healing across various MMORPGs. I do not get this in the current iteration of FFXIV. Because tanking for me, outside of VERY SPECIFIC instances where I'm required to double stack, or occasionally taunt in MUCH higher effort content, that does not make up a significant chunk of the game, is just turning on aggro gen and then basically being a DPS. Healing is mostly DPS but I occasionally should throw out a heal if someone's self sustain hasn't already done the job for them. I suppose being able to pull other players out of AoE that'll kill them is also sort've fun. But that's about the height of class creativity right now.

I don't see the point of taking a stance of "I'm the tank, I pull /stands doing nails while the group clears the rest of the dungeon without me" mentality in a game that doesn't respect class identity, job roles or enemy friction.
