There's a bug in the PvE only Wizard's Vault where the PvP objective "Participate in an Activity" appears every other day. Hopefully gets fixed soon, I think it's been around since the start
As long as these loot boxes stay in the game, I won't be. And enough with the BL chest comparison, those chests have 0 value and attractrion to begin with. Everybody was waiting for mount skins.
