Gold Weapons cost 4x refine material, and give 100% more refine bonus than White EQ,
but no suitable for F2P.
Better use Blue Weapons, it cost 2x refine material, and give 50% more refine bonus than White EQ,
which is affordable for F2P.
White Weapons is okay for F2P, but Blue/Gold weapons are better in mid/late game, you will feel the power gap when the time comes.
+4 Gold Weapons = +6 Blue Weapons = +8 White Weapons.
