This subject is a double edged sword. In one case you have players on daily collecting cores by the dozon so see no need for the economy to change. The other side are players that can only play certain hours a week or like me just coming back to d2 and only carry a small amount of cores im experienced enough to know not to infuse for the heck of it. In two days of play ive farmed 22 cores a few more would help but ive got to say they dont hold you back ranking/leveling up they just restrict what you can infuse or masterwork which is not good or fun. Im not saying its game breaking because its not and if bunjie remove them then the players who have loads will just have no end of masterwork weapons and those who dont can crack on without argument.
