Well, this change will work only in single. But is better then nothing :)

Hmm... as a matter of fact You can change this factors by Yourself. You don't need a developers to this. You must change some text files only.
Well, I play with my toy ;) a little and I see a very simple pattern. In case of Cobalts. If size of each group is below 7 then Defenders wins. If size of each group is 7 or greater then Attackers wins. It seems that in each particular fight there is a turn point where better is use Focus Fire then Spread Fire or more simply: If You have a huge army then don't waste time on Spread Fire because Focus Fire is better in this case anyway.
OK people. Mitigation problem is very interesting and is splitting fans on half thats why I create small application to check who has right. Nothing fancy :) Test application (call it little battle simulator) do a math for us. There are two groups of ships: Attackers, which use Focus Fire tactic. Defenders, which use Spread Fire tactic. You can setup a few parameters like amount of ships in each of group, hull, hull regeneration and dps. There is no shield but
@soltyspl, how is possible to make the same amount of damage to 4 ships FG by 3 ships SG? Calculations are totaly wrong. Besides there is no hull and shield regen too. And... FG group will up mitigations to 60% too becouse this factor depends on amount of damage received not amount of ships. Make math again and You see that SG group is dead :)
