For melee, I'd say edgeville dungeon red spiders is pretty good, good afk easy escape from small teams 
 
	For range/mage, moss giants in varrock sewers are good with 51 agility.  They have no range defence and big bones to bury and some decent alchables.  I did 28-86 range here, also pretty afk if you're reading reddit or posting on forums.
 
	Good luck bro
