Not that it makes that big of a difference, but I think most Nexon games were marketed towards the younger audience. It IS summer after all, and most students are either going outside and having fun, going to summer school for various reasons, or staying home and playing a game hosted by one of the [S]best[/S] companies. I think (just personally), that over the past year, Nexon has added too many events that grant AP potions, that it has made the game MUCH easier and convenient to the newer players (free pets/easy, good accessible items/ap potions). I actually enjoyed the game when it was a CHALLENGE to get to level 100. The players who stayed on longer and grinded received more than the ones who didn't. I know for a fact most players can get above level 90 without playing more than 3 hours everyday.
That's if your goal is level 100.
You can still reap many benefits if you continue to grind. Change your goal to 120-130 or something.
