This is a philsophical debate here. EUII was an event driven game, you played for the events. With HOI there are far fewer events. I happen to like it that way. To simulate Beck and von Fritsch in the game they both have low loyalty. If things start to go wrong then they will be more likely to desert you. If you want an army commander who is more loyal to you then it is up to you to replace Beck and von Fritsch. The choice is all yours, it is a feature of the game.
