Maybe, but I don't remember how long it took Lamar Cr and Caelus Cr to get staff banned.
Well, technically I think it is, but just because Sigma was constantly under weekly staff ban before they stopped doing those. I think she was only playable for 3 or 4 weeks in total.
Kalindra was banned quick too
Clover was put in the format election three days after she was released, but yeah this could be the fastest case of perma-ban in recent history.
