Blackrock Realm

Is it possible to enable this old Blackrock command? ".challenge playername"
It was used to play skirmish Arena versus friends (1vs1, 2vs2, 3vs3, 4vs4, 5vs5)

Because of the new Core we have lost all commands so it would be nice to keep at leats this one

if you do not like the idea of having a command, you can just make an npc "Wargame Npc" which works the same way.
Such Npc would allow to type the name of the player we wanna challenge. (always 1vs1, 2vs2, 3vs3, 4vs4, 5vs5 as before)

To avoid abuse you can set that players can not be challenged by ppl in "ignore" list and in case they have /busy state
