| The Yor could still have their super ability, just more powerful, like 2 or 3 times that amount, to a minimum number. So that 60 move ship gets cut to 45, making it slower, but not completely crippled. | 
If this were the case, I wouldn't call that a super ability.  Maybe a mediocre ability. If you have a ship that moves 80 parsecs, I am thinking 5 parsecs won't mean all that much, 15 might mean a little bit more than that, but still ignorable.

If it were a common effect, that all races had, it would be worthless as a super ability to the Yor.
I constantly see posts saying this needs to be balanced and that needs to be nerfed.  While a few requests are legit, most requests strike at the very heart of the game and the posters seem to miss the entire point.
Not everything is going to be balanced, it is not supposed to be.  Every race is supposed to have an advantage over others and have weaknesses others can exploit.  That is the point.  It varies the game play and makes things interesting.  Super abilities are supposed to be just that... Super.  A distinct, game altering, advantage. That is the way I see things anyway.
Is speed cheese?  I do not think so.  If you can give the AI a 200% advantage in economy and so forth by increasing the level of play, I think any tactic to beat the AI should be able to be used if the game allows it.  Brad wants to change the way we use speed.  Fine by me, I very rarely have a ship faster than 20 parsecs per turn.
So, the next time you travel into Yor space, take off your shoes and stay awhile.  Stop by one of our exotic planets and smell the pffffftttt flowers.  Kick up your feet, pull out your data flexxie, brew yourself a nice hot cup of Joe Joe Juice, and just relax....... We'll leave the lights on for ya.
