I'm not sure exactly where I stand within the Destiny community, but when it comes to masterowork/enhancement cores, I've never had a single issue. I do play a fair amount, but more than this, understanding how to get enhancement cores aside from The Spider isn't difficult in the least. While it is up to a certain amount of RNG, scrapper bounties are a fair constant for me and not difficult to re-acquire on a constant basis. Some weeks I barely play and mainly knock out the stuff on the director and through this, between cores popping out of gear, enhanced matterweave and scrapper bounties, I usually get at the very least twenty cores per week. And that's not counting Spiders bounties which are stupid easy to get. Spend about half an hour on the Shore and your guaranteed to get the ghost fragments needed for the necessary bounties. As for the bounties themselves, they typically take anywhere from one to five minutes to complete, depending on a bit of luck for the HVT bounties or simply going back to orbit and popping back in the zone the HVT is supposed to spawn in. While I understand the plight some people face when not having enough cores, all I can say is better understand the games underlying mechanics in how these items are acquired via RNG and use it to your advantage. Let extra crap go to your postmaster if you have the three scapper bounties. For the Vanguard takes no more than ten minutes, whether it's getting kills with your weapon types or opening the chest. Lost Sector scapper bounties shouldn't take more than five minutes, no matter the case. Crucible scapper bounties should only take one quicklplay match depending on which Crucible scrapper bounty you got. The ones for headshots and ability kills should take only one match. The one for capturing zones could potentially take longer depending on whether or not you get a control match over clash. Between all three characters and Spiders bounties, over the course of the week between resets, should take roughly: 30 minutes per character for 20 ghost fragments. So 90 minutes there. The Lost Sectors are five minutes each, if not less. So that's another 45 minutes total. The HVT's can be hit or miss. Assuming the HVT is still alive or available when you arrive to that zone, it should take about ten seconds to flatten any HVT. If not available and assuming you have to re-instance, lets just go ahead and say another five minutes per bounty. So, in total over the course of SEVEN days, it would at the absolute max take three hours to take care of all of Spider's bounties that deal exclusively with the cores. And that's not mentioning the fact you can easily pick up at least two cores per day for 30 legendary shards, which you should easily get while doing these bounties too. And that's not to mention the potential for a scapper bounty to pop up while doing these too. The math is against you my friend.
