Nobody was comparing to TF2 while saying Nexon shouldn't block modding. I personally believe they should block modding.
I was referring to this:
For the most part though modding is to further increase the enjoyment of the community and Valve knows that, that's why they promote modding as one of their companies main rules. Like I said, I don't care if we can't use the nude mod but at least let us mod for other things like maybe better outfits or whatever.
That is, they are saying that we should be allowed to mod better outfits as it is one of Valve's main company rules. My point is Valve's games are pay to play (the box fee), and Vindictus is not. So allowing modding would not make sense in this context, and be harmful to the game rather than helpful.
