Ship explosion -> The phenomenon that happen when a ship's hullpoint reach zero. Often accompanied with a BIG flash.
Have you seen another ship right next to/in direct contact with other ship getting destroyed as well while the other ship is killed? When it is not damaged in anyway before the ship explosion? That sometime you can kill multiple capital ship by just one hit?? Sometime when you are close to an enemy you take damage when they die? I want to know that.
I have lost multiple Novas from full HP while fighting other capital ships, thanks to the Nova dropping its shield at the last second.
I routinely lose Omens due to this phenomenon as well.
I think accelerated shields help mitigate this issue... It did for Shrikes, Furies, Tempests and Omens. Unsure how it'll work for a Nova.
It probably won't work. They're dropping their shield to defend from something else. 99% I don't see what that something else is, but it is very clear they dropped their shield and pointed it in the wrong direction due to the shield not being fully extended yet.
The AI clearly has some bad shield quirks with Pilums that run out of fuel. So that might be it, but I'm still not sure.
As for the Omens, they frequently have their shields fully up, and still explode because they dropped them at the last second. Not sure why they're doing it, it's probably a bug. Amusingly, I have yet to lose a single TT Brawler to this issue, so it may be an issue with omni-shield AI.
