They can blame it all they want on XP bot farming. But their true side appeared soon as they released the battlepass. The battlepass is the real reason we won't get Portals/bots the way we want, they won't have their BattleRoyale filled up or anything if they brought back bots and Portal XP.
That also answered my question if they were so focused on Leaderboard integrity, why didn't they reset all characters and leaderboards knowing that's how those players got the scores and weapons they use to kill everyone. Because they didn't care about bot XP, they were worried about Battlepass not working the way they want so they shut that sheet down
