Yeah, this is really in need of a nerf, honestly.
Well it seems this is probably more of a test of the delayed explosion mechanics more so than what is supposed to accurately portray what the batteries are supposed to be at release.
But it is bloody awesome to watch and set off.
I am more worried that cannons, which if they don't break blocks still have the damage carry through, will become overpowered now.
Say you have a layer of 5 advanced armor covering your batteries. A cannon round hits and breaks the first 2 blocks, but just damages the next three without breaking them. But the amount of damage remaining is still enough to break systems on the other side of the advanced armor.
Usually this was just a problem with armored rail dockers/computers, where aftermath inspections would show a line of damaged advanced armor blocks with destroyed system blocks on the other side of it.
But now? Now with a subsystem that detonates itself entirely if grazed? That is a huge chunk of system HP gone, not to mention the other internal bits it ravaged.
Would rather use a system with a single point of failure (the docker) than a system where any hit would cause a total loss of the entire thing.
One system where I could lose everything even if it was the only block damaged is better than another where I lose everything if any block is damaged.
Its cool that it explodes, but I don't see how that fits with the starmade we have been playing all this time.
