I am not saying that the comparison Darmstadt and Luton Town is perfect or meant to tell us what's going to happen with Darmstadt at the end of the season, but Darmstadt is repeatedly getting a point from their game and that keeps them alive. I think most people thought that Luton Town would be so far behind after half of the season is played, but they are not because they do get a point here and there. All these draws can add up when the season final has come.
I understand your point but as I said before the Bundesliga and the Premier League are quite different. Darmstadt is still quite weak because they don't have good players to compete in the Bundesliga and the limited strength they have will make it quite difficult to compete or get out of the relegation zone. We'll see how Darmstadt play in the next few matches and whether they can win or suffer another defeat.
Their next matches will face Dortmund, Frankfurt and Union Berlin so it is certain that they will miss the opportunity to get points. So it will be quite difficult for Darmstadt to get out of the relegation zone because they face much stronger teams in the next few matches, the opportunity to get points is possible after these three matches and I am also still quite pessimistic.
