If they wanted to cleanse every bug from a MMO the game would never come out. They have to beat out competition. A company has to produce results you numb nuts. You think Bioware is just going to sit idle while they feed a 3 year old project? Then they say, "You know what president of Bioware, I think the game should be perfect and awesome and have 0 bugs at launch. Can we have another year or two doing this?" YEAH RIGHT!!
They would close the project so fast. You think money just grows on trees? You think investors are just going to sit and feed something they feel is showing no results? You guys need to stop playing video games for a while and go outside. Go pay bills, go get a job, go do things that involve life.
They need to turn a profit. They get a sum amount of money. They use that money. If they need more time they have to host another meeting with investors and all kinds of crap to get more money. The process is all business. And until you understand that, these MMO's will just have to due with what they got.
