A system where you keep something that has no importance, here crafting and currency, is the worst you can do.
In fact, you can test everything you want… The only restriction is that it is rare to get a perfect weapon. And also, what do we call perfect?
One of my best weapon is a 369 SMG with pinning fire T4, blaze away T3, unyielding T4 and Maniacs T4. I can change, on it, blaze away and unyielding. Worst modifier is ammunitions at 63% and it has 77% damages, 70% stopping power and 80% collateral (and 80% mobility).
This is a perfect weapon for me.
For now, I have crafted 6 weapons since I started to monitor my craftings. I have got 5 times a blessing T4 when consecrating to orange. Problem is to find a good base weapon…
