I see plenty to validate the delay. Quite a few new features (to FF14) exclusive to Eureka, debugging and bug fixing, that sort of thing. Content released too hastily is content full of problems (Zenimax specializes in causing this with The Elder Scrolls Online) and Eureka came with very few. This is a trend SE tends to follow when releasing all of their content in this game.
Furthermore, what makes you think your opinion is fact? Because you are certainly acting like it is, and it isn't. Your opinion is your opinion, everyone else's opinions are their opinions. Agree and disagree all you like but no one has any right to call someone out on their opinions saying they are wrong, regardless of whether that is intentional or not with what is said. In fact, that is all that these discussions seem to be turning into: a flame war. If anything, just agree to disagree and let it go. No reason to be so pushy with your opinions and try to make people sound like they are wrong for their opinions if they don't agree with you.
