You have unrealistic expectations. This is why most MMOs avoid mentioning target dates, even when vague like "early april". Anytime you are woking with millions of line of code there will be bugs, sometimes in a spot completely unrelated to the changes being made. These bugs take time to find, report, analyze, and finally squash. However, you can help with this process by instead of complaining, log into the test server, actually test the game and /bug any problems you find.
