Unfair ? Modern warfare 2 is a mega blockbuster and really enjoyable game and it has unlockable, in no way these are game breaking but they makes it great to try and achieve some of the objective offered Im not tlakign abotu makign you a beef with 4 tiem normal hp or givign anybody god mod . But it kinda feels normal that If your charactere have been around for a long time that you get maybe few tool up your sleeve that some might not have anyway ... Thats why Im more into SP anyway Pvp will serve as a break at some point during campaign
I will probably enjoy it a lot I just fear about the durability of it we could say :p but thanks for sharing your points of view /respect
Edit : Just read last 4 replys I agree with these poitn of view but rankign woudl be cool but well Liek I said all my suggestion are more aimed at the fact that after 4 months of doing the same maps and same scenario I fear it might get repetitive unless they release some new features or options
