Wow...Anyone who says that people shouldn't be able to change the color of their weapons is plain ignorant. I understand wanting rarity in the game but that should apply to high stat weapons/armor, not the color of your weapon.
I've been looking for a purple crystal for a long time and cant find one. Unless, I want to pvp and pay a ridiculous amount of credits for it or pray i get it from a world boss. BULL. This really needs to be rectified soon
