So many people have complained about various issues, many are gameplay-orientated like weapon balancing and streaks etc. However most are about spawns, Elite and lag.
If people have a problem with this, it is right to complain. The game developers should be in no doubt as to the game they have created and how people feel about it. A few people have come on this forum to be "tough" or "cool" or "controversial" to attack those being honest, to criticise the people who are complaining and upset about their MW3 experience.
It may well be that some people moan about smaller issues or are even frustrated by their own style of gameplay or other people's, but realistically a huge amount of the community have problems with MW3 and it's all the game-breaking stuff, and all the things that are not answered by the devs.
Most people are upset because we all got a fair deal on older CODs, particulary the COD4, WaW overall, MW2 in terms of connection, and Black Ops, in terms of customisation, stats and patch information. In fact the more this series deteriorates the more we realise how spoilt we were.
When people moan, they are communicating their own distress, problems and frustrations, I don't feel it is right for someone else (who has lesser problems with the game) to pass negative judgement on those who have a poor game experience and those who make complaints. If the game is great for everyone, there will be few comments, and certainly less of the well-constructed complaints. These moans are not "noob" moans, they are decent gamers and I'm proud to be a gamer like the people on this forum.
This game has been a big disappointment for many people, the majority, partly because of expectation due to previous COD experiences, but also because the game does not work properly and the only communication from the developers is about more maps, more operations, more money.
Elite has been atrocious. The 3 primary purposes have been poor. Stats can only be viewed out of game, Clan operations - a massive new excitement - are pathetic if existing at all (and that's the same for clans on Elite in general), and the maps are out in a timeline and format which seems unpleasing to most. Nevermind glitches and crashes.
Lag is the worst played of all the series. 5 years on from COD4: MW and here we are, with relentlessly poor gameplay due to lag, host lag and inconsistent lag (meaning you cannot even adjust to the lag). Add to this the reduced chance of playability within a party.
Spawns are generally random and bad - in that you can die from a spawn with no chance and the maps are tight for whatever (surely well-intended) reason so this only adds to the problem.
Finally communication. This has been terrible. Misleading timelines, little communication about Elite and clan ops, so little working, even now, and nothing to start with, whatever has been told was tweeted on Twitter, not posted directly here. The devs appear not to be interested and have said nothing to hide that.
MW - 9/10
This has been the worst COD by a way. And this community deserve more. These forums owe it to the devs and the community to show that!
