Thought the beta ended, but can still log in it seems. Here's my launcher file if it helps anyone.
Anywho, it seems instead of increased base rates, it's a perm EXP/Drop event. I'm lv 33 and got 5 black stone drops so far, but that has been from just my time at Orcs. The amount of trade in loot dropped is similar to NA/KR.
In short, this is seriously the latest KR files but most of things new to the NA/EU client is still untranslated. I've yet to find any problems.
