I have been involved with competitive Call of Duty for more than six years now, I have experienced the ups and downs with the releases of each game. It is not by accident in the past that around the middle of every year people are starting to get tired of the current Call of Duty title and looking toward the future one. Every Call of Duty title before Black Ops 2 has stagnated after around 4 to 5 months competitively. Since Call of Duty got its chance on the pro circuit with Call of Duty 4: Modern Warfare there has been a simple rule set, a mix of a few or less game-types and a lengthy banned item list. With this new title, Black Ops 2, new life has been breathed into the CoD eSports scene.
This is almost 100% due to Treyarch and there interest into competitive gaming as well as their new CoDCaster feature. Treyarch voiced that they wanted almost everything allowed and nearly nothing banned. The biggest change was to have killstreaks enabled, which have always been banned and was supposedly an "obvious" ban in past titles. When the rules were first being put together in the beginning of the game some pros were saying that they were not going to play if killstreaks were allowed, but within a few months and tweaks everybody adjusted and now mostly agree that killstreaks make the game more enjoyable. Also with all the tactical grenade options and the new pick ten system so many new strategical opportunities have opened up that were impossible before. The game's meta changes throughout every event, people find better ways to hold down positions or break them. Every event has had that one play that has shocked the viewers and changed the game forever. This is what Call of Duty was missing in past titles.
With Call of Duty: Ghosts just 3 months away and with the next generation of consoles coming there is much to look look forward to, but you must wonder if Infinity Ward will come out with a competitively balanced game that supports LAN tournaments. Now this might sound stupid, but after Black Ops 1's success as a competitive LAN game everybody thought that it would grow. When Modern Warfare 3 released there was no tournament LAN ready system, and that hurt Call of Duty as an eSport. Now yes there were major Call of Duty tournaments in Europe, but no where near the size of tournaments for the previous game. Infinity Ward needs to support competitive Call of Duty, because if they don't it might be the fall of Call of Duty as an eSport. Now many people are saying that if Ghosts isn't what people want then we should just stay with Black Ops 2. Well, that would be a good alternative if the new consoles weren't coming out at the same time and not backwards compatible. Also a lot of the sponsors are not going to want to support an out dated game,for example the publisher Activision. Without publisher or developer support any eSport title will die off. If Ghosts does deliver the eSports support that the competitive community deserves then the sky is the limit, it will be such an exciting year for players and spectators. This year is just the beginning as long as the players have the developer's support.
