The game design is that you can not get enough items or adena in game unless you spend money on L2Store, and in time that has gotten worse, you get less from boxes in game , and also from L2store , so you spend more and get less, and they did that slowly like cooking a lobster so people will not quit.
My main class is also dagger , single target farming is slow
I used to get 3 forgotten ch 1 per week now I get 1 / per week , 75-90 box /day
But I do not force the game to the max , just play for fun, get what the game gives open some boxes, do game events never got anything good, I do not even do ios.
And yes the game has little to offer, but it is a good place to spend some free time, I am waiting for on update or something like that.
