it's not "poorly implemented"the problem is that there is a story but its very poorly implemented;
it's "not implemented at all YET"
it's still just a collection of scenes and short quest-lines, with a skeleton "story" to keep them together, but it's just a dummy to make the still-in-development game playable
IIRC they are planning to "complete" events for all the current mobs while refining the game mechanics, then tie them together with an actual story for the first beta release
