attack instinct attacks into fog tiles, is it broken? or intended?

[digimon666]

Sorry for my clickbait title thread, but i want to complain about random ranged unit that shoot into the dark (fog)/ to something we dont see. This will make some unit too strong in fog map.

The most notable example is spamming trebuchet and fully upgraded heavy catapult or (to lesser extent) longbowman as defensive option. You dont need sight, heavy catapult will take care most of stuff that comes in range.

I dont know the interaction of those with hidden unit like spy.

So given that, i will ask once again.
Is it intended? If yes, is it balanced in fog map?

Thank you.

this is simply a bug

Is it fixable?

Not meaning to be rude, given the age of this game i am surprised no one point this out.

it is known bug from long ago - about a few months - and sure, everything can be fixed but this seemes a little hard to when i first saw it.
