Currently fog is very frequent. In over 70% of battles I had in rocky canyon which is now a frequent map, there’s fog all around. Not just one area but across the whole map.
In theory fog is fine as it adds atmosphere but not when some aircraft only have IR missiles, which cannot lock on target if there is fog in the vicinity, even if there is none between 2 players.
I suggest that for now fog is removed, and in the long term allow IR missiles to lock if there is no fog between players.
