As a player, who does all 3 levels in Spire every week since the multiplayer feature has been introduced, I can say that 25 diamonds for an extra round in diplomacy seems somehow inadequate now in line with dramatic decrease in diamond quantity to be won from individual chests. Also, an increase in diamonds won from FS chests went up only by a miserly 50 diamonds. The 3rd level diplomacy has been also tweaked in a way, that we almost always have to take that extra round (I'm quite proficient in a diplomacy game btw, so don't jump in saying that I have to learn the skill). So, on overall, the last changes are definitely made to squeeze extra diamonds out of us. As a paying customer, I can only say that I haven't spent a penny on this game since last September, because all the recent changes trigger only a feeling of disgust in me. I have played a number of “free to play” games in my lifetime to understand that the direction here is somewhat wrong. A player must feel excited and happy playing the game in order to spend real money on it.
