Levelling is only fast if you go PowerLevel through it. A new player, heck if you go start on a new server, you will NOT be able to power level. Now since everyone is power levelling, no one really parties pre 40 so people are stuck doing leves.

A new player cannot hit 50 as fast as you, they cant power level, and it will take them time to get their first 50 by just killing mobs and doing leves and what not.

A lot of people need to stop thinking about just themselves and how they experienced it because its nothing how your average casual will experience it and nothing like how a new player will experience it.
