Wrong, its mainly the Oasis event that flooded the market with black gems. 12 boxes per day to each player literally for months does that. The calendar and seasonal server just help the whole situation escalate. But yeah I'm trying to keep this post focused on the calendar rewards, the month long oasis event is a whole another story. Again to my point, if Oasis and seasonal servers are already crashing black gems / concentrated gems, don't put them additionally in the calendar to crash them even more!!? If its still not clear, all I'm asking is for someone to look at each of the items in the calendar before releasing it and check its market price. If its already bottoming out, don't kill it additionally by putting those in the daily rewards. And vise versa, if something is unobtainable in the short term, maybe add it to the daily rewards to temporarily ease the players trying to get those items (e.g. Armor black stones).
