So GLU finally showed their cards today when they put the AR "Marble" on sale for 350 gold; which was one of the first "craft" weapons most people competed for. Everyone gets it for 350 gold, whether you earned 0 weapon parts, 5 parts, or 49 parts.
Weapon parts are completely worthless, except the 10 people that can actually complete the weapon. The other 2000 or so people with less than 50 parts wasted their time and hopefully nothing on energy to compete.
And for those of you who were able to complete the "Marble"; how much gold did you spend on energy to win those 50 parts? More than 350 gold right?, probably closer to 1000 gold, between the Global event and the 2-3 additional League events you had to get 1-3rd place in.
