I only really still do it for the exp too. If 80% of the players in the match are just going to be bots, why should I put in effort? The closest thing I can contribute to winning a match is by trying to herd the opposing bot armies into a remote corner of the map and screwing with their pathing(speaking of which, there's a hill you have to jump up on to the right of the grassy spawn area, I've had ~15 bots stuck on it at once before trying to run into it to get to me). It doesn't matter which team you join, every team is full of the mindless robots. The winning team is usually just whichever actually has one real group on it hitting objectives. The PvP itself isn't very alluring either, I can just pick MCH or BRD and run around getting kill streaks on bots and trying to persuade myself I'm actually good in a mode that has a skill ceiling lower than a lalafell. If they removed the exp, I can't imagine how many people would still play it. They just need to crack down on bots.
