AuctionGirl, my dear, you failed at fully understanding the revamp. What defines your HQ chance? Your final Quality. They use a non-linear scale of chance of HQ using numbers from 1~1000 to determine chance of HQ (which means, for example, 500 gives you 10%, 1000 gives 100%. Non-linear, weighted towards the end of the spectrum. Those numbers in the parenthesis were pure example drawn out of my... secret number stash)

If you utilize HQ materials, you gain a bonus to starting Quality, if using all HQ means your bonus Quality is 500 if i'm not misremembering what I read, mixing NQ and HQ gives a value between 0~500.

The projected numbers are so that, using your best crafter gear and the best of your abilities, you get up to +600 Quality if memory serves me well.

In the end: If you somehow can scrounge up 1000 Quality from all NQ materials, gods you deserve that High Quality item and you will get it
