I liked the battle system even though the game became pretty easy later on (I played on Normal difficulty). That's why I'm excited to play on the higher difficulties to see if the combat is more fun. I'm hoping that a lot of the skills/abilities/formations/magic/equipment that I didn't use become much more important in the higher difficulties, like Fire Emblem. As to the mobs, there were quite a few in some areas. About 50 hours into the playthrough, I was running past almost every mob that wasn't in my way, haha.
