Not sure I like making the champion even faster, it's already crazy fast. The other nebula ships need a slowdown though so you can catch up with them.
The Neinzul champion would be kind of like a raid starship, but bigger and modular
The Human champion would be just slightly faster than the fastest normal nebula ships (not the mysterious colony ship; only the Neinzul would be faster than that), and good against all of them.
The Zenith champion would be kind of like a bomber starship, but bigger and faster and modular (as it is now)
The Spire champion would be fast enough to go places, but still slower than some normal ships. Also slower than nebula ships that aren't the Malfunctioning Dyson Gatlings or the Ravenous Shadow or something.

Of note, the fact that the spire starship and the spire shadow frigate are comparable is pathetic. The shadow frigate should be better by far.
Likewise with the Human shadow frigate and the Bomber starship. (Although the human shadow frigate at least has bonuses)
