This is not one of those games where you're expected to play only one character, as playing multiple characters tends to be unfeasible due to the amount of very long character specific grinds. In these sort of games, they want you to play multiple characters, as levelling, and gearing up a character isn't nearly as grindy, and will even have things like account benefits to help encourage making more characters. Problem is, this game is seriously lacking in available characters, with only two not yet released here, when other games of this nature have about twenty, or more playable characters.
They could do, as games of this type usually do, where there there will be multiple base character types, with each of those having different variations defined by the weapon they use. I get the feeling they tried to compensate some by adding more grind to this version, what with levelling taking longer here, and more materials being required to crafts things. Although even then, without more playable character types, even the people these games are aimed at will get bored, and at least largely quit before too long, which is likely why people claim this game is so lacking of players in other regions.
