The new low-tech ships look great, and the change to burn drive is, in my opinion, the best of all the suggestions it has gotten.
But did the tempest really need a nerf? I don't think it was overperforming that hard. Thanks to its small shield it was really hard to use in mid-late fights. Sure, it smashes early pirates and pathers, but what doesn't? Most people were already choosing to use the scarab over the tempest, since it has a proper shield, and because small energy slots in general are better than in earlier versions. edit: and why is the Omen left untouched?
On another note, are there any plans to change or rebalance the skill system any further, or is it in a finished state now?
