Favourite BF game and why?

BF4 by a mile. It had the best maps, both original release maps and xpac maps were mostly all on point. It had amazing customization and progression with metals/unlocks to keep you playing, it had secrets and special items/weapons to unlock, It had one of the best varieties of weapons, gadgets and vehicles of almost any game out there, The weapon and vehicle balance was pretty good especially compared to other bf titles. And even to this day the game has never gotten stale & always have fun on it. I really wish they would give it an enhanced upgrade or at least add it to portal. After switching to series x the visual quality took a nose dive.
