Having seen what's been happening with the last several patches and events what makes you believe the delayed release will be "less buggy"? LOL!
They have crashed the entire network of servers including all platforms AND official servers and had them unplayable for extended amounts of time with event releases --- this is a huge DLC release. So, release some time on the 25th followed by hourly, then daily, patches for a week or more so everybody can actually play the game again.
