Seriously, why? High end crystals are either rare, hard to make, or expensive as hell on the market. High end mobs are hitting harder and harder. Servers are getting less reliable. A single reload screen at any high end zone and chances are you're dead meat unless you have full pen armors. Most importantly, there's no legit way to restore a loss crystal. There's no legit way of prevent a crystal loss 100% of the time. So this dumb mechanic doesn't benefit anybody, including even Kakao/PA. At this point, just add a pearl item or something that either restore or prevent crystal loss.
