Current iRO
Same Level: 100% drops
+/- 5 levels: 90% drops
+/- 8 levels: 80% drops
+/- 11 levels: 70% drops
+/- 14 levels: 60% drops
+/- 17 levels: 50% drops
Current Korea
Same Level: 100% drops
+/- 31 levels: Small Penalty (About 80%)
+/- 61 levels: Large Penalty (About 50%)
The problem is that 10 level difference is the optimal point for experience, but you're already suffering drop penalty. I would really like it if you could consider getting the updated drop penalty, because the current drop penalties are incredibly harsh.
Edit: The current Korea it turns out is only on their test server, on maintenance of July 28th 2010. I've updated it to show roughly what we believe the drop rate adjustment to be.
