This is literally a non-issue. You get matterweaves which guarantee drops. You are also guaranteed from scrapper bounties. You get them randomly from dismantling weapons and sometimes armours. You get them for schieving legendary rank in quick play. You also get them from certain story missions. You don't sit there and continually use up your cores every time you find a gun that has 5 to 10 light levels ahead of your weapon. the catch up mechanic for all new players definitely helps boost their light level and I'm sure you have 650 weapons laying around from random powerful engrams. all you'll have to do now is just constantly make armor pieces to increase your light level when you have your other three weapons at 650. It's not a matter of resources. it's a matter of how can I proceed forward the most efficient way. save what you have build on it and moderate your usage. I never have an issue with these cores because I know what I need to do. what people on the forms can do instead is educate players on how to moderate and find these resources. In any point in the conversation if someone's just going to respond and say that they don't want to do it: I don't know what to tell you. You can't help people who can't help themselves. It's really a non-issue and it needs to stop on this forum. There's like 10 posts of them right now active because people don't know how to obtain enhancement cores or just are too impatient or just don't care about the mechanic. Get over it. It's their way of getting players to slowly grind to Max light so that way they can't face roll the game. If everyone got to Max light level ASAP then everyone's going to complain that there's nothing to do. This is how RPGs work. whether it's farming for that one weapon to give yourself extra attack or whether it's leveling or whether it's doing extra missions because they're blocking the story from progressing etc. We all have to deal with it.
