there are many things that could have been done, but requires for a company to know their player base. They have events feedback in forum, use it to put events that ppl like. Maybe something like a discound on whole shop, that is nothing special but it is nice(china has that for medal users). Some good login ninja, honestly I would have saved gnw for sakura for this week and put her free for log in, but they put it for monthly so they should have put someone ppl want and is seful as her(no troll characters). Or they could have put 3.0 this week, if you tell us we get 3.0 weeks before and do not implement it during anniversary week, events should be really really good.
