BFBC2 question

Alright, so at this point in the game, I have everything unlocked for the classes I enjoy the most. (Medic and Engineer) However, I only have like half the unlockables for Assault and Recon. And I was wondering if it's a bad idea to keep playing Medic and Engineer before I max out the others.

No it's no big deal, it won't hurt you in any way. I still have some Recon and Engineer left to unlock. I rarely play those.

I have them all unlocked ... if you want the trophies, unlock 3 guns and leave them alone ... that's the only perk of the one's you don't want to play with. I have all 4 unlocked (Vehicles are boring) and now I'm STRICTLY assault, so If you see me in your squad, stick close and I'll keep your ammo loaded

Idk I just feel like obligated to unlock everything, and I feel like it's weird not unlocking anything when other classes still need stuff. And also I don't hate the other two classes at all, I just don't like them nearly as much.
