"Casual Breakthrough" is only going to cause more problems than solve.

1. You're splitting up the player base even more. The whole point of PvE is that there's no humans on the other team. Eventually and mark my words, Casual Breakthrough or whatever Casual modes come to core Battlefield will turn into a sweat-fest just like how Warzone's Casual modes did, and at the same time it will make the core modes worse because there will be less players in those games.
2. The player base is already massively split because of RedSec. When people in the US and EU complain about the atrocious matchmaker and bot backfill not working in CQC modes that's how you know something's seriously wrong. And for the record, low player count regions have been dealing with these issues SINCE LAUNCH, it's only just been magnified because of RedSec.
3. It's based on 'Warzone's Casual Battle Royal' mode, the irony however is that Warzone's mode gives FULL XP for anything involving Bots. Why would I waste my time progressing at a snails pace in a game that doesn't respect my $70 premium entry (which had progression against bots that was working fine at launch in Official Matchmaking!) when a F2P game like Warzone has a better implementation that ironically tries to respect your time, lets you just chill and have fun whilst still progressing the game and battle pass at the same rate that everybody else does. Battlefield 6 was supposed to be better, not worse.
4. People asked for Portal Full XP with bot backfill, why is this not happening. Low player count regions suffer without bot backfill. Instead we're getting modes that are only going to make the game worse because the player base in these regions are only going to further split apart.
5. These changes have broken bot backfill in Official Matchmaking for CQC modes, games never begin when bot backfill kicks in.

Instead of trying to solve the issue by running in circles and wasting everyone's time and your own money, just make a separate set of Verified Portal modes that give full progression against bots, similar to 2042's Co-op mode. Fix the matchmaking that constantly splits up players. Make the official matchmaking lobbies persistent. And please fix bot backfill in official matchmaking. And make the challenges REASONABLE HOLY HELL!

This issue was amateurishly solved in 2042, yet here we are again. Instead of improving on 2042, we're making it worse. BF6's Progression remains inferior to 2042, and that's a **bleep** travesty to say.

As a result of what is essentially a worse version of 2042's bot backfill and Progression experience, I regret buying Battlefield 6, especially with the knowledge that was possible at launch is no longer possible.
