Converting to Chinese or Japanese are easier than English, and they have a bigger market / demand there.
well, i like your reply after reading. this is exactly what i do, have a few sets of armors for different maps. i enjoy playing the game rather than just blind rushing the level. people who blames the game design much which felt hard to level,is just because most of them want to level it fast without wanting the game hard difficulties. people like you and i or whoever who enjoy the content of the game, really enjoy playing with the tactics. imagine i spent like 3-4 days doing nothing just focusing to initiate shinobi class empty note quest and to obtain the yellow petal flower. the fun is there, just wait patiently and try different methods to get every map passing thru. inevitable, mage mobs are a bit irritating and have almost 99% accuracy on missile attack @@" but the game design ain’t that bad, at least i feel it is challenging 
not always the human side to win the battle
This is one of the reasons I love using an utility class to play on maps with 20+ Lv. difference, lol. Quite rewarding collecting materials and things this way :v Also, there are ways to prevent or force the monster to target other things which is funny and useful.
