Consider the typical visibility scenario in Indian subcontinent
Now imagine having those isolated haze circles at all of those labels and that too with a fixed ceiling AGL which has no scientific explanation.
Some argue that METARs should be done away with altogether, so all we would end up having is clear CAVOK conditions throughout this and similar regions which is only going to make the matters worse as far as realism goes.
The solution is a thorough rework of weather model to have server-side blending of visibility conditions and meteoblue has enough data for Asobo to work with. The only missing piece seems to be the will and effort to take up that leg work.
