I am not against better sights but I am against better sights as standard. With the exception of the laser rifle and the plasma cannon, current sights are fine.

Iron sights have been used for over 100 years to great effect at ranges well beyond what we have in DUST. They are cheap, easy to use, and nearly indestructible. But most importantly, they're cheap. When you need to arm hundreds of thousands of soldiers, you don't give them top of the line optics, they get the cheapest thing you can find that will work every time. That's just economics.

To give you a comparison, a quality set of iron sights for a modern assault rifle will run you about $100 US. A quality red dot that will hold zero on impact and not break under typical grunt abuse is more like $500. Assuming you have a quarter of a million individuals that need rifles, it would cost you an additional $100 million to give them red dots over irons.

Now consider that many of those individuals will probably never fire their weapon in combat because they have jobs in rear supply type positions. Is it really with it?

tl;dr yes give us better sights but only with weapon customization. No to better standard sights.
