people don't like changing their match up settings, that's the experience i've made. generally. if you go into this type of content with your npcs/bots, thinking they're in any way helping you, you're wrong. if you go into this type of content thinking you will get good XP/Hour, you're also wrong.
the bewitched forest, or enchanted forest/woods, is simply a means to farm rares.nothing else.
so if you go into this and bring your NPCs because you don't want to be alone, make sure to set the active recruitment setting so that real, actual useful players, can replace your NPCs at some point.
if that is still not good enough, and you hate playing with others, there is always the option to set a password and restrict others from joining you, MPAs included.
there seriously is no excuse to not follow those little rules in content types where everyone knows that Enemies have HP pools directed towards MPAs and also hit like trucks.
