I do agree with you to an extent, it does indeed suck that they pushed it back 2 weeks. However, it wasn't as if they wanted to; this expansion is going to be the largest one for the MMO so far, and they want to make sure it is acceptable to be playable by the playerbase. I'd much rather them take extra time to perfect any flaws now, rather than have a botched product be pushed through to their paying customers. That would make me more upset than a expansion being pushed back a little. Yes, it did unfortunately mess up people's schedules, and yes it is frustrating. But, that's just life. You gotta roll with the punches and adapt accordingly, if something doesn't line up the way you want, then yes, it's okay to be disappointed but you got to brush it off and keep moving.

Personally, due to college it lines up perfectly for me with this new release date on Dec 3rd early access since it's the last day for the semester for me. However, even if it hadn't lined up perfectly I still would have found the time to play, granted it probably wouldn't have been a lot but the game will still be there.

Take this opportunity for this month to catch up on things that you may have figured that you'd push off until EW, like leveling new jobs/crafters, or maybe even exploring side content that you haven't done yet. There's plenty of things to do in this extended downtime that you can put your time and energy to. Best of luck!
