price increase

Quite quietly, price increases have been implemented. A month of a troop master now costs 40 gold previously 30. You have to pay 3 months in advance to get the same price. With 6 months there is only a discount of 4%.
The Journeyman builder and Apprentice builder also experienced a price increase from 7 to 9 gold that is 28-29% more.
Some other mini packs may cost less, but those are not so important to the game. Just some nice extra's The troopmaster, journeyman and aprentice are vital.

I would appreciate it if the deflation of the gold was made up by increasing the log-in reward:
3 days in a row log in: 1 extra gold

30 days in a row log in: 5 extra gold
So if you log in 30 days in a row you get 15 gold to compensate for the higher prices

i did not say it was not allowed. But we can buy less for the gold now (inflation). So i think it is just to compensate this with the gold you can get for free in the game.

You can not buy mini packs for longer times. They just became more expensive.
