There is no point in levelling, its absolute waste, its there to just give you something to do and keep you playing more, but content and events should do that, not choring out the same mob 5 million times.

For casual people who have busy lifes it shouldnt feel like it will take a year just to hit a 50, some of us casuals would actually like to enjoy the game and do activities that is usually locked to those who have 30 hours a day to play.

Like I said, if you dont like it, you can reduce it yourself or become casual.
