On the Issue of Power Creep and How It Relates to Nexon

I say Nexon does a good job handling the power creep that was handed their way but hey I actually play the game.

Handed their way?

Who is it that keeps releasing classes that are more powerful than any before them, and then "revamping" the old classes to match?
Who is it that keeps creating equipment sets that have higher and higher base stats and set bonuses?
Who is it that keeps releasing new and more powerful scrolls and scrolling aids (wards, etc)?
Who is it that keeps adding more equipment slots?
Who invented potential, and keeps adding more tiers and lines to it?

Hint: it's not the hackers.
