Well, mate, if we're going to get passive aggressive about it, my point is simply that warzone is slightly different to other battle royal franchises, in that it is intrinsically linked to another game, one that is one of the most popular games of all time. So it's possible that they don't have the sort of focus on it that other companies would have, as there could be an element of it being a side project to the main game, to some degree. I could easily be wrong, it was just a comment. They obviously make a fortune off the in game purchases, but they don't strictly relate to the types of things we are talking about, such as expansion of the game etc.
I wasn't being passive aggressive, unless where you live calling someone mate is being passive aggressive?
To your bolded point, I would say the fact that Activision have been trying to do everything in their power to
unlink it from Modern Warfare tells you all about how important it is to them to make it its own thing going forward, and avoid the issues you're saying. They've already separated the two of them out in menus, separated the battle passes, and tried to link it with Black ops more than MW, it's failed for them so far though because MW is a much better game than Black Ops and has a very loyal fanbase who'd be pissed if they completely unlinked them after a year.
Warzone is very important to them, it's much more of a consistent cash cow year on year than a single release like Black Ops is. It's also huge for them to integrate with new CoD games year on year because it has such a massive player base and they know that by doing so it'll incentivise people to buy those CoD games.
I suspect the main reason we haven't seen a new map yet is simply because they're probably afraid to change the formula, which is why we've instead gotten updates to the map itself and Rebirth, the new gulag etc. The Warzone map is also absolutely massive compared to other BRs which probably plays a part.
