Probably not since Bad Company 2 had a terrible system. The reason is that you would unlock everything by rank 26. The only think you could go for are pins, insignias, trophies, and weapon stars after rank 26. I have played Bad Company for around 700 hours and I'm rank 50. To be honest, it's not worth it. DICE said that they would work on the ranking system on Battlefield 3 so it's probably different.
