Check the official thread for more in depth information.
Well for starters, you're off to a great start looking at online, as while the campaign was fun, it's short and not perfect.
Things you need to ask yourself:
Am I willing to play objective based matches? Am I willing to have a lower K/D ratio?
If so, you are in great shape. If not, I do not even want you to be on my team on Rush, as that game is being ruined by people who simply hang back and snipe.
How much do I love perks? There are no super power perks in this game. The only things that are close to them are things like slightly increased running speed, slightly more damage/defense, increased destruction, etc. And DICE has made it so that you can only have very very few of them, with things like Red Dot scopes having to be sacrificed for extra accuracy.
Am I willing to have weaknesses and short commings? DICE has constructed the class based systems so that you CANNOT own everybody. Even as a Recon with sensors and C4s, your biggest weakness will be running out of ammo, and you'll require an fellow Assault for that.
Watch this video and if you will NOT do these things, or at least willing to learn a different gamestyle, then you're good.
