I mostly stick to portal due to the server browser and more diversity in types of gameplay, more consistent game play, and more control of what I want to play, when I want to play, and how I want to play... 🙌
I've noticed TDM is more fun inside portal than when Dice runs it outside of portal.
Portal allows gamers to easily play with and against the same groups nightly and that creates a sort of competitive comradery that the MM system destroys via total randomness and lack of any map and/or group control, not showing which map is coming up next, etc.
Playing TDM outside of portal requires me quit after the game starts when it is not the map I enjoy, etc.
MM inefficient randomness is more complicated and wastes more time waiting for games to start and backing out of half finished games and out of maps that I don't want to play..
Dice's BF 2042 MM system is a buzzkill compared to Dice's portal server browser system and that results in less consistent FUN and thus most likely less gamer engagement and thus less Dice profits long term...
