Since the stories of being knight-elite have unintentionally been slowly hijacked by the half of the forum that was never actually knight-elite discussing their experiences with knight-elites, I thought it might be a prudent decision to make the thread we need, rather than the one we apparently deserved.

The main stumbling block I come across when playing with 3* knights is when they send a friend request.
I like to be nice on my runs. I think being nice is something everyone should try. However, that doesn't mean I want to carry every random person through Sewer Stash after finishing this Roarmulus Run. Usually I just quietly ignore the new mail, and move on with my day. However, then they corner me and ask me why I haven't accepted their friend request. There are only so many polite ways of saying "I don't like you, go away."
