Impossible. Each win in crucible gives 3 marks. So it takes 33.3 matches to get 100 marks. Each match takes about 10-15 minutes, so on low end it takes 10min x 33.3 matches= 333 minutes, which is 6 hours. Multiply this times 2 so that's 12 hours of playing, over the course of two weeks, since marks cap at 100 per week. It takes only 30-40 minutes to beat level 32 PoE... So it actually is far less time playing the game to "earn" an etheric light playing PoE than it is playing crucible and earning marks to buy 1 etheric. So you are dead wrong, I make a much better point than you. Do the math buddy.
