Not exaggerating, just something I'm not aware of personally. Those items are the only thing keeping me from plat so if I could find a resource to get me all those in an hour, I will shit myself. I know people complaining about that grind has been a huge thing in the fanbase for some time (especially among the anti-pvp crowd like myself). I just gave up, and it sucked enough that I didn't even attempt it in the DS1 remaster. Personally, you saying you did it in an hour sounds more like an exaggeration to me when you've got people like this (not that I don't believe you):
Trying to engage in PVP to actually get the covenant items is really hard in 2021 unless you play at the right time, level range, weapon range, and area. Reading over various forums, and YouTube confirms this and makes me wonder why FROM is so anti-offline players in terms of covenant rewards...

Nameless king is my favorite boss in the Dark Souls series, but he's also one of the few I've never died to before. I'd place Champ Gundyr And Friede from DS3 over him, personally. Bloodborne has probably a dozen plus I'd place over him. Same with Sekiro. That's all fine though. I guess it could be subjective. There are just certain bosses I've seen people collectively complain about more than others like Ludwig, Isshin, Demon of Hatred, or Orphan.
