Love the sound of this idea and really do hope that somewhere along the lines something like this is implemented into the game, However we cannot expect to see this any time soon it really depends on Kovu LKD and whether he feels like doing it, Also there is the spam one would receive with the requests to fight. I do think Kovu LKD should add something similar to this to the game but I honestly cannot see it happening that's just my view, Other then that it is an honestly great idea!.
