Lift Fog at base?

[worldfamous]

I recently lost a game where my opponent was in the fog at my base, hit it, and then took 3 days to make his next turn. When it was my turn again, I foolishly skipped the replay because the board looked clear. Of course he , finished me on his next turn. I'm bringing this up because I was thinking that maybe our bases should have sight for any space in contact with them. What do you guys think?

P.S.
In case you're wondering how this scenario occurred, I should not that it was a 2v2 game. More fog, turns take forever, and the replays can be exhausting.
