Hello.
I did a post asking for the current item upgrade rates and the people answer me somethings like the current upgrade rates system is "good".
Someone answer me this :
Upgrade Rates:
[WEAPON]
Grade 0->6: 100%
Grade 6->7: 30%
Grade 7->8: 25%
Grade 8->9: 20%
Grade 9->10: 15%
Grade 10->11: 10%
Grade 11->13: 5%
Grade 13->14: 4%
Grade 14->15: 2.5%
[ARMOR]
Grade 0->4: 100%
Grade 4->6: 60%
Grade 6->8: 40%
Grade 8->9: 30%
Grade 9->10: 20%
Grade 10->11: 10%
Grade 11->13: 5%
Grade 13->14: 4%
Grade 14->15: 3%
And then i asked what happens if you use a white stone.
The answer was that Daneos changed the system and now if you use a white stone the item cant get distroyed but if it "fails" nothing happens but if the item "brokes" it will be decreased by -2 upgrade levels.
So, i made this post to ask for a change in this current system because it is impossible to upgrade an item more than +11 or +12 if your not a "bugger" or a "hacker".
You need to be super lucky to can upgrade an item level 70 to +15.
Maybe you can return the previous system of white stones to make that if the item "breaks" this not decreases in upgrade levels.
Note: this is a video that i made where you can see that the actual system is too hard to upgrade an item.
Thanks for your attention and sorry about my english.
