Overalpresentation of the tech-tree

The return of the actuall tech-tree is something I hoped that happend (So thanks), the feeling of progression it gives is awlays nice to see. Though this can ofcourse be improved with exclusions I'm also a sucker for completing it all the way. One thing that I want to see improved is the presentation of it. 

The main problem at the moment is that it's kinda hard to destinguish the techs from eachother. As no name is given without hovering over. Certainly for the first couple of matches it becomes kinda a chore to choose which tech to take. As I said you get used to it but that means that the only thing left are the stats. I would like to see that the spheres currently used for representation have some more information on them without having to hover over it. 

Seen immediatly: 

- Better Icons representing the results of said tech.

- Better representation of finished or not (a different shade of gray isn't as alluring as bright green)

(Challenges): Your position

Hover over: Turns till completion
