COD Is all about reaction timing. Classes help but ultimately it is twitch skills that win. Destiny is very similar to halo in the sense that even if your the one at the disadvantage, your skill can overpower the other player and leave you on top. Again this is true of cod - but you have to be far superior to your opponent to make comebacks from major disadvantages. So overall - I say bring it! I like to root out campers in COD anyways.
