And let's be honest. Using this enchant you'd invest in protection potion anyway.
Nope. DD runs to obtain ~10 solo ESs, place each on a cheap bracelet, and hope that backbreaking lands on one of them by pure chance, rinse and repeat if you don't like backbreaking rolls. Reforge if desired. There, I just told you how to make an end-game handgear that's pretty damn cheap to repair without using protection potions
As someone said, I really don't find it surprising that NA Nexon decided to put in end-game stuff in gacha. In reality, they really don't have any other way to leech money off players besides gacha and reforge sales, and with the Eweca Gacha being pretty much worthless in terms of rewards, it's not a surprise they would try to revamp it to increase its sales.
Mabinogi's one of those games that everyone should understand to be heavily pay2win. Sure, reforges do nothing if you don't have the stats, but with double training potions, skill training potions, and various other cash shop items, I can probably reach my current state in the game in 1/10 the time of making a fresh character if I had enough money to plow through everything.
My point? Mabinogi's been pay2win ever since reforges (I'd actually disagree with release of White Horse being the starting point because it was still obtainable through other means) and people who would throw money at Nexon will continue to do so. The only way the regular players are going to be able to take advantage of this is if we work our asses off and save up enough money to buy the ES from players who received it from gacha by pure luck.
