I'm with you on the N's. Like, if instead of 1k per pull with a 100 pull limit, why not make it 2,500 a pull with a 40 pull limit and no N's, or adjust it for whatever the percentage of N's is. Only good thing about N's is the +1's, but they could add those onto the enhancement or rares.
I like your weapon skill idea too, Like if I can tske a weapon from skill 1 to skill 6 w/ 16 rares, why not let me do that with one upgrade, instead of making me do 5?
