When do the training wheels come off?

So what you're saying is that you were able to successfully handle the basics of the game because past experience had prepared you for it.

Did you ever consider that not everyone has that past experience?

The game literally has a quest at the begining that won't let you proceed if you don't reach certain ilvl. Quests and dungeons give you gear that has tags indicating that it's suited for certain jobs. Upon reaching Garuda, you've done plenty of quests and dungeons already.
