Hello, I'm interesting in this post too.
What is the general sense of the changes of the new world? Why was it necessary to change the monsters property? Why relocate them to other locations? Why are they spamming skill like crazy? Centipede example throws quagmire whole screen. Tatacho stuns themselves with hammer fall once a player gets into the zone of visibility. (My idea of the monsters are based on information from the irowiki.org)
My favorite character in RO is ninja. And I was pleasantly surprised by such things as a black scarf and a Sapling card. But the customization of the new world is killing all fun of the game.
