As soon as I saw that raw EC was needed I didn't read.
You never, ever, use raw currency as a material, save for a few exceptions.
What do you think the server would be if all materials - Mystical Elixirs, Pure God Stones, Ancient Emblems, r8 mats, Event Tokens, mounts, flyers, cogs, wwi, supply tokens; everything - was exchanged into raw EC?
Want to make a few potions? Use 5 ec and get x amount of y potions.
Want to get some +20 vit stones? Buy some off God's giving for 3 ec each.
Want to engrave your ring, necklace, belt or cape? Use x amount of ec and go for it.
Want an r8 set? Drop 100 ec per roll and good luck.
That fancy fash over there, or those fancier flyers/mounts? Use those untradeable, EVENT epic coins and you'll look snazzy.
Want a new cube or ws? "Are you sure you want to exchange X EC to purchase Y ornament?"
Huh? Supply Tokens? Oh! You mean those Event Epic Coins you can't trade!
You take away the middle man, you cut off the economy as a whole, where the only thing that can be traded is tradeable gear based on its stats, or in this server, a ring, necklace, belt or (Ascended Dragon) cape.
The economy has already been reduced to the state that the only things sold are tomes or engraved ornaments, and by removing the "middle man", the materials, and replacing it with EC you're just making it worse.
And yes, I know Ancient Emblems aren't a thing anymore. I listed them on purpose because they're a clear example of what happens when you take out said "middle man".
