Sounds nice best but it has to be delivered with the AI properly utilizing them. That was one of the fixing in 1.8 for the currently existing traits and I'm wondering how does it work now to those that had some mileage with 1.8 - good?
well - depends. in general its an improvement as commando units are lead by commando leaders (all alpini units use alpini leaders from what i saw). the little annoyance occurs when a country used all non-commando units for its inf and has still more inf on the field - it wont use commando leaders for those.
for example turkey has 20 inf divs and 20 leaders, 2 of them are commandos, 18 non commandos. so turkey will use the 18 non-commando leaders for 18 inf divs and two end up without a leader, instead the 2 commando leaders stay in the leader pool as long as there is no commando unit produced.
i potted this little thing for turkey, the rest has no trouble with that new tweak. its just that turkey hasnt enough leaders in general - for the rest of the world its better, esp for ITA.
so what i know ai uses traits like this:
LW - GAR
commando - commando
only
panzer leader - ARM, MEC
offensive - ARM, MEC, MOT
i just made a quick game some weeks ago, and iirc its still using tank busters for INTs sometimes, but not sure
