My guess for why gathering and crafting are spaced out from level 1 is the game is trying to give you time getting used to the game before throwing more stuff at the user.
The revamp will allow crafting at level 20. Honestly the first 20 levels go so fast there's no point in trying to craft anything before that.
Once getting to lvl 80 - you're going to have to grind through Khitai, and T1, T2, and T3 raids before you get to T4. Don't think you're going to waltz in with crafted blues and kill the Emperor. AoC is not an easy mode MMO.
Take your time and enjoy the game and learn how to play your class in a way that works for you.
