Little can properly word it and even if few manage it then they get covered by massive QQ. What people fail to make blizzard realize is the following:
- Leveling is filled with pop culture references. Its funny by the first consumption, problem is that after a while they get old and people are fed up with it. You cant possibly convince me someone can laugh from the same jokes by hearing him over and over and over and over agian.
- Leveling is not engaging. There's little to no quest in entire picture that requires you to focus. You literally can spam whatever skills you have without paying any atention to it and you will still kill the enemy without problems. Clicking on objects or collecting some random items thrown around the world really isnt that much engaging or fun I might add.
- Leveling teaches you next to nothing about your class. Your character learned interupt spells, but there are little to no consequences to miss a interupt in open world during questing, in a dungeon or raid that can mean a wipe. Your character learned agro drop ability but there are no situations where your character has to use it, in a raid or dungeon that can mean a wipe. Your character different spells which consist of your rotation, but there is little to no situations where you have to burn down an enemy quickly, keep aggro for DPS NPCs or heal them before they die, in dungeons or raids doing sub-optimally any of those can result in a swift wipe where everyone start to blame everyone, rightfully so because the game didnt teached any of them anything and they all believe they did all ok since during leveling nothing like this ever happened.
- Leveling is inconsitent with the end-game. Nothing that you pick up during the leveling (except last blues in 89~90 areas) help you in peforming at end game. Putting out fire on the bay in Thousand Needles or on the harvest orchard in Northshire Abbey doesnt teach anyone how to act during raids or dungeons. Turret section dont teach you how to DPS/HPS/TPS in heroics or raids. Tasks during leveling must be similiar to those players do in raids in order to know whether they are doing the right thing or not. Explaining it with outside game guides which slowly become THE ONLY solid decalogue on how to succed in end-game IS A DEVIL DAMNED COP OUT!
TL : DR
Leveling is:
= filled with pop culture jokes and references which get old really fast.
= is not consistant and too different from the end-game.
= as such it doesnt preapere you for end-game at all.
= is not engaging in any sort of way.
