Which BF game's unlock system is more "addicting"?

Hardline is garbage.

Its insanely low TTK and terrible map design evoke Call of Duty more than Battlefield. It’s just a COD knock-off with a Battlefield skin. And yes, the premise of Cops v Robbers is also terrible. The single player is garbage as well. Hardline is not a good game, IMO.

Not gonna play a bad game to unlock stuff…
