yes, I saw those in videos, but I played few days a Legacy account when I started my current account that I found a link from a player name MAO and can get the parts. Like you mentioned, that was Legacy. Now you just need a credit card with good credit line and buy as many you want and good luck to get the part you need.
Things changed and the rest of games are doing the same. FREE GAME FREE GAME JOIN FOR FREE, by the way, you need to play 20yrs to get a free relic or collect the enough to waste in just one part in 20 years.
