Brilliant job really, have you considered the idea of joining our staff at COH2.ORG and make these statistics threads real newsposts? I am sure the community would love them as well as Relic (Relic especially loves this kind of infographs with statistics )
i still think ghosting should result in exactly what it is. a ghost wire / sand bags, meaning you can walk right through them til physically completed.
I started to play again 1vs1 and I admit I found it strange that vetted sturmpioneers with flamethrowers (Feuersturm Doctrine) weren't able to beat Royal Engineers. After playing more games I will make a final opinion but for now I believe they are overperforming for their cost.
Interesting and detailed, I'll make sure to point it to Quinn Duffy, perhaps it will make him think about that, or just have a good read!
Design/Balance wise I am not sure, some of the buildings/tech options are too general and they might offer too many options/units for the COH2 unit roster. But the starting point seems good and they would certainly be "unique"
