Legion: Why leveling is different

I got my beta key 6 days ago, from one of the wowhead give-aways and have been playing Legion BETA ever since.I want to give my PoV about something that people have not talked about, leveling in legion and why it is different.For most players leveling was a chore, the means to the endgame. Rushing content, skipping content and finding the most efficient way to hit max level. Being one of these guys, i was surprised with what happened in this BETA test.The artifact weapon is the real game changer here. Upgrading the artifact weapon, making it more powerful and cooler can be done from the first hour you obtain it. While you level, you can find different treasures/side quests/ explore areas that will give power to your weapon.Why is this different from normal leveling though? Simply because any improvement you make to your artifact will actually contribute towards the endgame power of your character.This is my favorite thing this expansion. Progression starts from Day 1, and the player feels an actual connection to this powerful weapon he obtained, which he will carry all the way to the end of the expansion.
