Gaming differences

Just watched my good friend Tom play a game of zombies on the classic map Der Reise, and it dawns on me just how good at zombies he actually is. I'm getting quite good at zombies now, very much thanks to watching videos by the best solo zombie player Syndicate, my highest solo round is now 19 compared to 9, and I'm really starting to learn how to control the zombies, but tom is just in a different league, he controls them so well, knows when to run and when to just move to the side so he can group them.
He played with three other people none of them bought perks, and generally sucked, whilst Tom decimated all just running and gunning, on zombies that's bloody impressive, as he didn't rape train. I hope to get as skilled as him, maybe even better some time soon.
