Hi Alex,    Seems like ur icons are showing differently than the oryginal ones. The one which he is making is the standard picture/avatar or skrimisher cav, possibly due to modification's which you have installed. I could be wrong but I think this is the issue here with you thinking he has different cavs.   

Hello, yesterday I was playing nomad and a guy was playing with Romans, and I thought he was using champ cav, but later in the replay I notices he had different cav in the stable. This is new? Is a mod? A bug? What am I missing?

If we want to work on that, on "fire decision" mecanism could be based on the density of friendly troop in a zone.   Archer/slinger would only fire at enemies if the density of friendly troop in a "kill zone" of the weapon if below a given threshold.    One could imagine 3 different leves of threshold for that that could be controlled by the player ("safe", "moderate", agressive") the same way that the "attack stance" is controled. SO in term of computing, you don't make a computation per range unit, but per zone more or less. Technical development could allow for improving accuracy (that's already implemented) and other parameters with this new mechanism in mind

I totally got off my cellphone when watching this video. Thank you very much for sharing this interesting piece, @wowgetoffyourcellphone! With upcoming questions on pathfinding issues (e.g. #8506), the 11:45 minutes long video 'RTS Pathfinding Explained (and Why It Feels So Good When It Works)' by YouTube channel PlayZeroSpace gives inspiration, what could be the scope of the further development. Quote from the video description:  

As Release 28 has already got the codename Boiorix, may this thread be unpinned, please? This might avoid confusion.
