Yer, they announced they werent going to have an open beta. The had a closed beta which is basically private testing with a handfull of people.
This was propably their worst mistake, if they had a public open beta, im sure 1000s of people would test it out and alot of the problems customers now face would be fixed before release props.
Now we are stuck with a crap game.
Beta Patches probably wouldnt work, testing fixes can be done in the enviroment of their offices.
The reason they didnt find the problems in their small beta testing was because there wasnt many people online at the same time as the testers, because its pre-release date.
Now they can test their patches as there are 100000s of players online where the problems start to show, so it should be an easy fix if they can identify what the problem is.
Like a few people said on the CTF TS server, they tried to release it so it came out almost exaclty a year after modern Warfare 2, so everything was rushh to shit
