To be fair, the new system shows great promise, but it's not very satisfying right now.
Let's give concrete examples :
- if you want to level up sturgian archers for instance, you can have 2 groups and add "heavy armor" to the group with high level archers and tell them not to fire. The system gives priority to tier 3 archers in the "low level" group, great. However, the tier 4 troops don't have priority in the low level group before the tier 5 troops, instead it seems to fill the group randomly.
- I got the same problem as above with melee, horse archers, and cavalry.
- some orders are interpreted wrong, for instance "charge" only changes their position.
- when I create an infantry group in group 5, they often position themselves with too much space between each other in the future battles (not the first time though). I suspect they act as if they were cavalry, even though they are not mounted (including the captain).
- we don't have access to the "protect the left flank" kind of orders that the AI uses for cavalry.
- sieges show an order of battle as usual but the order is completely overridden when starting.
