The Reality of our "Content"

It's very hard to accurately assume most of the Maplers just go to those monsters and grind. As for myself, I grinded on LHC and Stronghold but also did optional Theme Dungeons and Party Quests.

In reality, a lot of MMO's have the same concept of MapleStory. There are many monsters in the game, but only a select few have good EXP or good drops.
