Dexless DW vs. dexless NW

What everyone generally means is "most bosses kill nightwalkers in one shot, meaning no amount of survivability or 'skill' will save them. Other bosses (like pap) can cause a lot of cheap/annoying deaths, so maybe it looks like they require more skill, until you lag a little or get stunned at the wrong time (mostly unavoidable) and die. They don't suck, they're just extremely disadvantaged.

It's called partying like I said before.

We've got: Pap, Zakum, Horntail, Pianus, Manon and Griffey.
Pap is survivable.
Zakum is not the boss I want to solo at 120.
Horntail is .... y'know
Pianus is 1HKO
Manon and griffey are survivable. However, they're maybe not worth it to hunt them at all.

So Pianus is IMO the only problem, but it's quite easy to find a party for it since it's hunted a lot. It has a crappy respawn time, so you might end up not even finding one.
