I look at the systems and outcomes. A good design does reward those that can make the time investment and/or have higher levels of skill. But it does not exclude those that don't.
It's usually just lazy design to make a "hard" game. And you shouldn't put 90% of your game design efforts towards appeasing 10% of your target audience. Now, if your audience IS all hardcore, skilled, committed players, then it's OK. The Dark Souls series is a good example of this. They're punishing to the point of frustration for the mass market, but serves their niche audiences just what they were looking for.
The Diablo series is a good example of a broad-market game (that went a bit too far focused towards the niche market with D3 IMO). You can grind and increase your odds of getting top tier drops, but the base game at lower difficulty levels is enjoyable for many without all the grinding.
So, much depends on the intent of the design. Is this ECF contest meant to heavily favor the prolific posters in a particular thread? If so, don't change a thing, it's working as intended.
But if it's intended to reward ECF members from a wider cross-section, it's more than a bit flawed.
I'm not proposing a minivan soccer league "everyone's a winner" mentality here, btw, I hate that crap too. But the minivan soccer league shouldn't pit the players against a Premier League team (playing to win) and expect the majority of the kids to have much fun either.
