It would defeat the purpose of playing the game if you can just fork over money to skip what makes it so great, no?
I think so, but then again, I've never min/maxed of powerlevelled... I don't really understand that playstyle. But I don't think it's our place to decide how others play, as long as their playstyle doesn't interfere with others.
And that's why I suggested the "I Win" button, because I ALREADY see people on the live servers powerlevelling left and right, using server resources for that purpose. So, why waste the server resources? Just give them their end goal, and then those resources will be more open to those that actually want to play the content.
Those that want to play the game "as-is" can ignore the feature and just play the game, and those that don't, can play the way they want to. I, for one, will be in the former category.
