Because it does not really make any difference. Normally you would not sacrifice escorts or enable enemy to fire from 2 broadsides just to get rid of a modyfier. You could do this in some minor instance and in dogfight style fighting on a small table. Unless you are covering 90% of the LOF with 1 salvo and using those 10% with the rest of ya fleet, but thats a cunning manuver, not an exploit, right? )
So if you do this i will deffinately have a point about dumbed down tactics.
Sig i got ya point about spreading but no-one here EVER thought of it this way, and probably during the last FAQ either so stop making that crazy statement - no-one plays it like that.
