1) Activision has failed to notify people of an age restriction until a week before the tournament, leading to several teams travelling to the event with players under 18

2)  Without lean, console and dedicated servers in the game, Activision has turned the PC community against them and seems to be moving over the Call of Duty franchise towards a complete mainstream, console based environment with a new release hitting the shelves every year. With downloadable content, which will present players with further costs,  that might be stretched to a new release every two years but with millions and millions buying the game the decision makes sense from a business point of view

3) One obvious problem is that the matchmaking system requires you to connect to the internet to have your LAN games, something which can cause problems at many events. This reminds me about Blizzard's statement of no LAN game in Starcraft 2. Oh wait they are part of Activision family now...

4) The multiplayer maps are also too cluttered and big for competitive play, making a balanced game virtually impossible. This already lead to the main gametype changing from Search & Destroy to Capture the Flag but even this didn't help the matches and actually made them rather dull. From interviews and talks with the players most of them are already bored with the competitive aspect and with the lack of mod tools it looks like new usermade content isn't going to be something for the distant future.

Wait, PC gamers! Before you send Bobby Kotick a thank you letter, know that it wasn't they who did it, but rather the gamers who took Infinity Ward and Activition's attempts to lock down the game as a challenge. And bring it those gamers did, managing to hack in the developer console and enable the ability to set up dedicated servers. Keep in mind, the game hasn't even been out a week.
