I just did another test using a higher yield warhead missile system
The test block is 4-30x30x30 blocks to make one large block of adv black hull, no shields applied.
The missile system used located on one side of the turret consisting of 16 launchers x 64 blocks of missile, beam, explosive set at the value of 25 on explosion absorption and did not appear to due to much resistance and left a nice clean dug out of the adv blocks, with bits of blocks still fresh from the explosion present
So I set the explosion absorption value to 95 and repeated the test to the 2 test blocks
It did core out the first block and showed signs of some resistance upon receiving a second impact
This the impact creator of the second test block clearly shows a reduced impact creator in size and resistance of the individual missiles launched by the imprint of the resistance pattern in yellow damaged hull.
My conclusion for a server would be to also alter the config set up for the missiles reducing there overall effective output, the blocks themselves can only divert a certain percentage of the total output of a missile system alone, a ship consisting of a single layer or even up to a 3 layer system of block defense would have "0" chance of any survivability once the shields have been reduced to "0". For the effort and time to make Adv blocks with there settings is absolute waste of time in this scenario.
The stock setting of current is way over under balanced for good gameplay balance for effective combat in ship to ship fighting. You only end up using a portion % of the actually game, again this affects economy, trading, business in lue of building a system that's over OP for a single strategy fight.
