Today I found a leg ring and wanted to reroll one stat on it. But now one enchanting cost 1 royal gem. So i spent almost 1.5 mil on 1 reroll which turned out bad btw. Are you nuts, blizzard? To enchant a good stat on ring or amulet can easily take 10-15 tries and you are still not guaranteed anything.

There's a trade-off to requiring a Royal Gem when enchanting a Legendary Ring or Amulet. In this case, it's that there is no longer a gold cost for enchanting these slots. This is important to mention because, normally, gold costs scale higher each time you re-enchant an item.
Say you enchant a Legendary weapon ten times. That gold cost climbs exponentially, from a few hundred thousand to possibly the tens of millions if you hit a particularly unlucky streak of not rolling the affix you desire. The cost for consistently re-rolling a Legendary weapon or Armor piece is effectively on a curve.
Now, take a Legendary Ring or Amulet. Instead, you have a flat cost every time it's enchanted (one Royal Gem). It's a high initial investment, but will never get more expensive, unlike enchanting other items. This isn't on a curve at all by comparison. In addition, this provides a sink for gems, which we didn’t previously have.
In both situations, you are gaining additional chances for the affixes you seek in exchange for a gold and resource sink. The approach is just a little different between the two.
