I can definitely see where the OP is coming from. Just recently, I've had all three that resulted in wasted time. Copperbell Mines, under geared healers that couldn't keep me alive during the first boss due to DPS that couldn't kill adds fast enough, causing me to have to pull the whole bridge at once.. which is fine if you have a good healer. But, a fresh 50 in 50/55 gear? In Haukke, I've had tons of wipes on the first boss and the 3rd. If you the group has two under geared DPS, good luck trying to beat the 3rd bosses adds before she wipes the party with blood rain or whatever. And Pharo Sirius... I don't think I've ever had a group that didn't wipe at least a few times on the first and last boss. Especially Siren... I've had healers in AF2 not be able to heal/esuna well enough to finish that fight.

When I'm trying to get the HL-R done for the day, I'd much rather get WP or AK. I know that my time will net me the tomes. With the other three, you may get tomes or you may get an hour+ full of wipes followed by rage quitters. Nothing like wasting over an hour in one of the three new dungeons only to never finish it and then have to queue up again for the daily.
