I'm looking at maybe trying to create a simple UI addon that will let me add players to a list with a tag of DNH (Do Not Help) above their head and next to their name, and also in the chat box.
My reasoning for this is that there are a lot of players that are not helpful in any way and I would like to keep track of these players so I can return the favor ever so subtly.
I suppose I could also add a KOS (Kill On Sight) function for enemy players as well.
