The ratio to reach top speed is 2.5:1 now, so your ship has to have a lot of thrusters and little armor. With advanced armor, that is 5 thrusters for every 8 blocks of armor, not factoring in other systems. Then 10% of your ship will need to be overdrive modules for 100% effect. Then for every 20 thrusters and 20 overdrive modules, you'll need more than 5 more thrusters. If a 'capital' ship does this, then it will essentially be a destroyer or fast cruiser, not a real capital ship. Going up against another capital ship, it would be shredded.
But this is a valid class of ship. It's an escort for a real capital ship. There won't be a 'battleship' that can reach max server speed. By definition, that won't be a real battleship, since another ship could forego the speed and stack on double the armament and 4x the weapons.
As I said in my post, I'd rather see thrusters primarily affecting accel to the max speed, and thus fighters would always be able to out-maneuver and get to whatever side of a capital ship they want to be on. The engagement might get up to server max speeds, eventually, but again, I'd like to see it take a large ship many minutes to get there. And the fighter would get there first and still be more nimble. Thus it could be on the backside of a ship going in reverse, and stay there if it wants to. But the new changes do definitely help balance it toward the fighter a little more.
