There is a constant confusion about which game we discuss at the moment
If as in theme's title - DG - there are no torp launchers could help you to "slow foe down". If it's Jutland - maybe it requires another theme?
As for me I never write in Jutland's themes cause I don't play Jutland and have no opinion about it...
As for "smoke war" I doubt these factors affect situation so much we could even notice - again - in DG
From my experience - neither sun, smoke nor wind can't help you much to overrun computer
It's advantage is quite more sensible...
