Lack of tanks in the game

[Zirael_Foxfire]

[...] Both are things tanks just need to learn to deal with being the leader of the groups, if you never ate trash for other people's mistakes/not operating at 100% yourself then the role would be meaningless. That isn't to say that I take the insults as hits to my self-esteem and cry myself to sleep after every DF, it's just that to me, tanking is supposed to be for people who can take punishment and not let it get to them.

When we're talking aboout low level dungeons where you're still learning your, possibly first, job, I disagree with what you said above. You should not get grief for the first 49 levels of the game. Even if your gear is bad and you lack cross class abilities.

Again, I can load SCH, go to let's say Halatali or Thousand Maws of Toto-Rak, cast Protect, cast Selene and do NOTHING else for the rest of the run, just follow the party. Noone will die. And noone will say a bad word to me.
I can load Archer or BRD with lv10 bow and armor. Spam Heavy Shot for the whole entitety of the run. Noone will question my DPS. Noone will complain it took 45min to complete dungeon.

Try going to Halatali or even Sastasha with lv10 weapon and armor, get paired up with lv23 synced people.
The grief tanks get is due to imbalance in how game systems punish mistakes and shortcomings of a tank compared to healer or DPS. Game systems and balance issues make tank job much more stressful to level up, and Devs need to change those. 3k gil and 25k exp extra once per day won't change how stressful and not fun it is to level up tank. Especially for newbies who don't know dungeon layout, pull order, proper rotations.

I agree with you about need to make effort to manage threat when it comes to endgame tho. I remember massive issues my LS tanks had with Spiny Plume for example. And they enjoyed ironing out who, where and how pulls it. Or T4 Knights/Soldiers. Or Titan Ex. Or Moogle. But leave that to end game, where you have all the tools and gear at your disposal.
