It would seem recent changes were made to the daily dock bonus, making diamonds exceedingly rare to come by. Mines and fruit trees continue to drop less and less metal and cider. Coalition materials aren't even guaranteed with 5 star wins, which really sucks when you are AA and can only farm AA and GA bases. In top of that, some nations are so impractical in end game that finding GA/AA Japanese for example to get silk is almost impossible.
Of course these are all intentional roadblocks put into the game to further force the purchase of crowns. I have an idea - make a quality game with fewer bugs, better balance, better incentives for war, and actual war replays. Do that and people will happily spend money on the game. You only find subtle ways to FORCE players to spend money when you're not confident you can produce a quality enough product to where they will WANT to spend money.
