Its every 21-24, and its still not the fact that it can spawn every 21-24hrs, its keeping the gear rare, it needs to be fairly hard to kill, not pop that often, and low drop-rates on really good drops, if the whole server can get the item in a month its not worth puting in the game.
I could just imagine having the HNM's in 11 at 1hr respawns.
