This is a great NM to camp if you're a chip-farmer like me.
Not very many people camp Sophie, so competition isn't a worry. Also, you can farm bees while you wait for her to pop. So even if Sophie doesn't give you the drop, you still make a lot of money. To me, Sophie isn't the "aim" when you camp her. The goal is to make money on chips and such. The Beestinger just makes a really nice bonus to shoot for. Even without the bonus, you're still a winner.
NM hunting has never been less stressful.
To the person who said SE nerfed the beechip drop rate, you're wrong. I've been playing since early last summer, and the drop has pretty much stayed constant the whole time.
I highly recommend this NM for lowbie players to get their feet wet. The drop is only worth about 8k, don't get too excited, but it's still a fun NM, first one I ever killed.
Oh, and I'm actually 3/3 on Beestingers if I remember right, so it doesn't seem to be an uncommon drop.
