Can only attach one agent per army ?

[Rigby]

In previous games you could attach all of them to your army, now they restricted it to one. I personally hate it because you obviously will always choose the Champion for the gaining experience. Hope this can be modded

Decreased unit upkeep is something you want if you're fielding many armies. Experience is easily earned.

The champion is seriously OP right now, 30 turns in and I have a full gold XP army thanks to a few battles and the insane champion training.

Yes another regression...

The champion should be limited to a certain level of experience given. In other words, a unit should only be able to get to level 5 or so from training alone.

Right now there is no reason to put anything other than a champion in the army. They promote all units to level 9 and can give you a campaign movement range bonus.
