The broken FFXIV Holy trinity

[Viridiana]

i stopped reading when you said this.

This is my point exactly. What a broken game when the Dps can tank a Huge boss like Titan .

Seriously, it's called overgearing. Try doing that in a mix of AF1, Darklight, and maybe a piece of AF2, with Garuda weapon tops. Try doing anything you're talking about at the gear level the content is actually designed for, not the level that was available when it came out. Hint: it's not going to work.
