About crafting and a little question

1/ These are 2 guns i'm storing in my inventory, i'm using the first one :


The problem is, i've spent about 1500 gold for crafting that first gun but still can not replace that crit line with dmg,% inc dmg or craft a better gun ......
I use both 2 methods :
+craft that 2 guns with 2 other guns with no stats i need
+craft that 2 guns with 2 other guns,each have atleast 2 line same value ( or lower a bit) to the first gun
I want to ask what method should i use? the first or the second?
And what is the % to craft a better gun with the first method?
Can someone give me a better method to craft a better gun?

2/ Does Deluxe membership have far higher chance to earn cube from mobs than premium?
i ask this because sometime i earn some very good legend items which have 1 orange line and some good gem from cube. Deluxe's price is double than premium, so does the chance to earn cube double too?

 

I'm sorry to tell you that you wasted 1500 gold crafting a legendary that isn't as good as some extraordinaries that you can craft for much less gold.

Here is a post that tells you how you should craft if you are interested in getting the best items in the most efficient way possible.

Basically, start over using blue and green items and make a proper extraordinary. Then, save the gun you are using now, and use it as one of the items in slots 3 or 4 sometime in the future. Same with the second gun.
