Well last night I decided to get back into Blops for a while to get a "Prestige Token" to spend on another Custom Class in MW3. I was at level 48, and it didn't take terribly long to get to Prestige. What I was surprised at, was how much better I was doing in Blops compared to when I had set the game down. Granted, I still got my ass handed to me... but I was able to use tools I never laid hands on before, napalm strikes, turrets, predators.
So I did Prestige, then played a few games (up to level 3) to kick the Prestige Token into gear. So I need to wait about 48 for my MW3 to populate with my new token for my seventh custom class.
So while I'm not even mediocre yet... at least this shows I have improved a little. BTW... there were still a lot of to be had!
