P.S.
Both Fyrons and PVK's stances on combat work for engagements under 400* ships....
Once you get to the magical 400 barrior forget everything you were doing before. Its a complete new system of fleet setups etc... Due to the fact that the game cannot handle placing all those ships effectivly.
This is where the BaseShip vs Battleship really shines if your baseship is designed properlly vs your opponent. As the first 3 to 4 rounds will be complete slugfests. So it is recommended that you punch very hard on the first round. And then soak the damage during the receiving round.
For less than 400
If a player is using the BB system against your base ships. Attack him on warp points... This will be to your advantage. If they are using SD 's or the engine one on the APB BB... They will close to a range where your BS will be able to hit the BB and inflict some damage. And always set you base ship to target nearest nearest nearest... with a Point blank then ram stragety. Your shield depleters and engine destroyers will have a greater range and when one ship slows down an enemy BB the next BS will destroy it
Another advantage of BS vs BB is that when you lose ships vs happiness... it does not affect it as much as you have less ships
