Why do people avoid getting better at the game?

[Silver-Strider]

The dungeon difficulty I'm referring to belongs to the bosses. What later dungeons have a lot more of than earlier ones are a guaranteed wipe if the healer eats dirt and there is not another job like RDM or SMN to raise them. If you're a healer in these instances, I would worry a lot less about getting a tank who knows what to do, and make sure you're staying on your own feet. If you die, the wipe is pretty much entirely on you.

Or you can get a Tank that knows what they're doing and can solo practically any boss from ShB-EW with little issue.

The last dungeon boss that I'd argue has any semblance of challenge is the Mist Dragon in the Burn
