I would love to see PvE modes in the game! It could either be something like Halo's firefight, or simply a Vs AI in the already existing arena game types. If PvE does get added, the most important thing you must do is make it possible to earn XP, and make it so that the things you do contribute to the battle pass's daily and weekly quests. I've noticed that there is an "Or" between completing something in the arena and in the Battle Royal, and it'll be a good idea to add another "Or" for PvE, as getting kills and points would be much easier and abundant compared to PvP.
