You should "Copy & Paste" the last dragon slayer event instead of making the current event x10 worse.
Current Event: 4,000 Enchants + 800 Dragon Slayers = x2, +13s (gold save tickets worth 15b/ea).
You should at least leave 1 event that can breathe some new life into the servers instead of crashing the market and driving people away.
