I would say it's worth it. Coming from years of BF2, I was skeptical about scaling down to 32 players. However, in the beta I feel amazed by how much the "war zone atmosphere" has been amplified. it doesn't feel like a smaller battle. There's atmospheric effects like snow/dust clouds, debris flying everywhere and buildings collapsing into rubble all around you. There also seems to be more explosions. I've never experienced that kind of intensity in a multiplayer war game before.
Also, the squad teamwork incentives have been ramped significantly. You get bonus points for healing/repairing/re-arming your squad mates compared to helping your team mates. Just last game I got almost 5000 raw points (before the after-game rewards bonuses) just for being a good squad medic.
The only thing I'm now unsure of is how things will change in a conquest mode map. Currently, the rush map squeezes everyone into specific areas, so 32 players doesn't feel small. Perhaps it will feel smaller when we can free roam. But then, the map sizes will probably be smaller as well.
