It's not just the leviathan, Punishing one is also screwed up because they didn't use any common sense when they implemented it. If you have the stronger P1, you are going to get smashed by the weaker P1. We've been talking about that since it came out and CG does NOTHING about it.
They hated weak zombie, but they gave us a ship that's a weak zombie and don't seem to be bothered by that either.
They want us to spend money, but then they punish us (no pun intended) for maxing out ships by breaking fleets in multiple ways. It would be great if they actually communicated, but they don't seem to care to want to. All they communicate with us about is "hey, here's a new shiny that's going to make your entire roster useless if you don't have it!" (It might be buggy, but don't worry, we'll fix that by 2030.)
