So the main defenses I see people saying in here for keeping cores are: 1.) Save your cores and manage them well 2.) It makes the game more impactful in some way, but no real specifics are given (or the inverse of the game will be bad in some way if they are removed. Too easy?) 3.) This topic is over whined about so lets not talk about it anymore 4.) Personal attacks on people wanting cores removed without actually contributing anything None of these things really address any actual negative to cores being removed. They are based more off of feelings than any actual impact on the game. Cores reduce build diversity. They promote one or two sets of meta gear and that is it. If you love meta than great! If you wanna try out other potential unique end game builds it will cost you greatly. That is a big negative. A much more specific reason than the ones listed above.
