It doesn't take a genius to predict that we will be seeing frequent posts about hero order being all messed up in pvp.
When someone fights a team like Kai, Kira, Black Diamond, Aria and they bring Shade, Bunny, shadowblade, Ponti they are going to make a post about how the defenders took their turns out of order. The attacking shade is going to kill Kira (if he doesn't dodge), then the bunny is going to remove the body moving Black Diamond into the second fast spot behind Kai. Black diamond is going to take her turn before the attacker's bunny since there is no place holder for Kira's original spot.
This will become the new post we see on here a couple times a week just like when Ponti reincarnates or when someone flees in terror.
Maybe we will be rewarded with placeholders when hero sorting is added.
