I don't understand this mentality. I want to get in and out as fast as possible. I've done the dungeon multiple times and i'm just there for the reward. Hell in most other games that isn't even speed running, that's standard operating procedure. Speedrunning (the way I know it) is skipping everything that skippable (not that applicable to FF these days), pulling as much trash as can handle, and ideally the boss too and blowing everything up.

That's my preference. If I get a slow tank i'll suck it up, but you (not a personal attack) annoy me just as much as I annoy you.
