I'm going to say something that many don't like to hear it.
The restoration system was introduced to help people from accidental failures.
People, being greedy and all, took this opportunity and abused it to the point they had to constantly regulate how much and how many restorations they can do.
And every single time, greed overcame the need and people found new ways to abuse it all over again.
This resulted in people loosing items, as they didn't catch on with the change of rules every time.
Until, well well well, GREED AGAIN, started asking nonsense questions like spoiled brats just before they do something naughty... "Hey dad? if i broke my sister's bike in half, will you be mad? -No child, as long as it is an accident.. *proceeds and breaks it* - hehe, dad i broke it, by accident, sorry. -ok son, here is a new one.
Same, idiotic in my opinion, question here. "Hey, if i enchant this and i fail, will you give it back to me?"
This was a good system to help us recover items that in any other case and year of L2 they wouldn't even discuss with us about restorations if you failed a
draconic bow +15--> +16 for example back in the day. And we killed it.
So, back to hard pills to swallow, I simply don't understand the frustration of some players that support denies to inform about restorations now...
