Just my unpopular opinions, though probably no one cares. This is not just directed at FFXIV but many modern mmo.

1. Pets should be a privileged item that few should have. In many modern mmo everyone has a pet. Makes the world looks like that of the Golden Compass.

2. Titles are like medals and likewise should be a privilege. Nowadays many mmo awards you with a title for taking a dump in game. Everyone has a title now. Behold Dilgid Aigit, Devourer of Hundred Pies!

3. Clan names/tags should be of different font size and color than that of names. Same for title.

Can't think of more atm but I am too opinionated and critical to not have anymore.
