I'm positive I'm not the first to bring this up, but I'm gonna do it anyway. Blocking makes me feel icky, even when it's been put off and only used as a last resort. When I unfriend someone (typically for being a pest, and not taking advice to cool their jets with any sort of seriousness) it would be super-cool if I was immediately removed from *their* friend list as well.
I think most wouldn't notice. Maybe it's the fact that I'm an 'a' player and appear at the top of most player's lists. I don't want to be mean and resort to blocking, but it's been necessary in a few cases since simply unfriending someone hasn't made them go away, so to speak. I don't want this to turn into a facebook spinoff with regard to friend lists and such... but a two-way unfriending would be a really convenient addition for me.
As an aside, this feature would likely also help quite a bit toward the whole "street thievery" issue that has been hot in the forums for a few weeks now.
Thoughts?
