Tougher Notorious Monsters are very welcome. Also it's great if an item is rarer than more common. People say that everyone is going to have it at some point because it's an MMO. People played FFXI for years and never got dalmatica and that was an NM drop. When you saw dalmatica it was impressive. There were a lot of things like that in FFXI. There were also a lot of alternatives so that people who didn't have as much time could get stuff as well. It just made things more varied.

But still I don't think the issue with notorious monsters is how tough or challenging it is, or how rare it's item is. I really feel it's the repop. When an NM that has a rare pop time due to something like lottery spawn and maybe an hour respawn and you see it, it makes your heart jump. The feeling made fighting leaping lizzy exciting even though it takes five hits to kill. I was trying to get a Thalassion Targe and all I did was kill Slippery Sykes twenty times (not exaggerating). The fight was incredibly boring and still took much longer than an hour to finally get my drop.
