you wrong, even we use the crown to train troops, the French cavalry doesnt need 1 hour for 100 medals. If you dont know about it, just practice until u can. Make an easy example, 1 game you can get 15 medals, for 7 game you can get 105 medals. 1 game costs 5 minute (example for prepare all the scout and find) so u just need 35 minutes. Then the time for retrain dead troop, you still have 25 minute. For a good calcutale player, 1 hour can make a lot more. Sometime people said other players is cheater with the thing that they can not do. its so ridiculous!
