Don't think I'll get around to a video...
As in Hylfire you have a chance for trooptalk:
After battle your mentor, Acrimaldo, might give you an opportunity to talk to your troops. You can get a boost from your level 1-3 troops, anything from gold, rage, mana, new units etc.
That means if you carry for instance Miners in your army or in the Reserve you can get 1.500 gold pr. hero level. If you carry Gardeners they can change into Royal thorns etc.
I have made a post in this forum about which creatures gives which bonus:
