Keith actually has plans to imminently redesign the ion cannons quite a bit. However, in light of all the nerfs to player stuff in this build, he said he didn't want to majorly buff an AI weapon at the same build.
So expect that in the next version. I love the decorative cannon notes though, that's hugely funny.
Note that the antimatter starships were a rare case of the ship actually performing more or less like we wanted, but players having really off expectations because of its name. Hence the rename rather than a more proper "fix," because to fix them in the way players would be expecting from the name siege starship would be to break other parts of their balance that we didn't want to. Aka, I don't want
a ship that can cream forcefields and other structures from the other side of a planet. There is nothing that enhances about gameplay.
On the other hand, ion cannons are one of those things that have just slid into disuse and disrepair while other aspects of the game grew up around the one-feared masters of the AI planets. So it's time for a rejigger of them, and I thought Keith's plans were pretty cool for that.
