There is a difference between killing bosses in Coil compared to dungeons im sorry to say. I don't think I've had a problem once in any dungeon in this game where going in freshly blind my party couldn't down the boss the first or second try. Going into Coil even knowing all the mechanics for each boss, you're still going to wipe a bunch before you get it down on farm. they're not comparable. With that said, speed pulls on trash in Coil are necessary to eek out those extra minutes to utilize for boss attempt. Outside of my daily roulettes, I don't run dungeons, so yes, I want my Poetry as quick as possible so I can get on to more important (i.e Hunts, Pvp, Coil) content, so speed runs are the way to go.
