While it might be difficult to get a 5 Star governor with fleeting, getting 5 Star Scientists and Admirals is definitely possible as you can deliberately train them on science ships or your main fleet. Later in the game you have so many leader lifespan techs, that it really doesn't make a difference anymore or you just genemod the trait out.
So I think fleeting is okay where it is.
However, I do agree that there are too little -2 negative traits which leads to almost no customization if you want venerable. There are lots of good additional trait mods and I think the devs should put some of those in vanilla.
It also give lack of customization with very adaptive.
I just want to make a race that very adaptive, nomad and fast breeder, just to see how much I can spread it around the galaxy. So I just need a single -2 that not non-adaptive.
