For me, the "level grind" is just a distraction; in my second generation, I have done much better at levels 15-25 than I was doing at 25-29 last generation. It's also interesting to see your actual skill with a weapon rise with your in-game proficiency, giving the illusion that it has much more of an effect than it actually does. One reason this mod is so awesome is that you get the constant little bit of satisfaction when you gain experience and level up, but the real depth of the game itself is almost completely detached from it. You get all the benefits without the cost. For a truly stark comparison, evaluate the grinding in this game with Diablo III or World of Warcraft--games completely founded in grinding with a game on top as a distraction.
