So i had an idea while sitting in the shower this evening.
In a game where everyone is constantly changing their player name, why not have an option to give people nicknames on your friends list?
Example:
I add someone named Bob to my friends list.
Bob decides he wants to be funny and change his name to P0K3M0N M4ST3R while i'm offline.
I log in and see someone on my friends list named P0K3M0N M4ST3R and i have no idea who that is
But-- If we implemented nicknames on our friends lists, i can type "Bob" and no matter what Bob changes his name to, i always see "Bob" on my friends list.
I dont know how feasible this idea is. But i think it would be a cool feature.
