Why dice not give away Valentines Day pendants anymore

It could be as simple as them deciding not to give them out anymore. Also, since you have posted this in the Battlefield V forum most likely this is not a thing anymore since the game itself has ended its development cycle.

I think I need to point out that it is a recognised fact that Battlefield 5 announced the suspension of updates in 2020, and until 2022, the badge I mentioned is still being issued, and the decision not to distribute without any notice is issued, so the official is really ”too respectful of players“
