I know all that shit. What? Do you think I'm some noob? What I'm saying they are too fucking rare, and some items want like 3-4 per upgrade. They need to add a grindable source to the game or just have them be a rareish drop from bosses or some shit. It's nice they added the spider thing but the price of shards increases every time you buy one, and there is no way 1 if those cores is worth 40+ shards. If you notice, they made purps rare across the board. Before you would get 2 sometimes per public event. So by your 3rd shard you buy from spider, 40 shards, that's 14 purples you are dismantling. I understand they want people to try out new shit, but people still like their favorites. People will probably have different sets of gear for over, pvp, and now I'm betting there will be raid specific perks too. That's a lot of shit to upgrade. I already have a few pieces with right perks, but im afraid to upgrade them because I have little cores left.
Another thing... no one is doing public events now because they drop nothing. Even the mats it only drops 2. You are better off putting on a ghost and go hunting for chests which drop 2 as well.
I heard fags like Gothalion go over this shit on one of his streams while I was at work. Someone was bitching about the core thing and it seems like they told bungie at some event meetup to do this. But lets not forget, streamers like him and datto and other fags play this shit for a living and have literal 1000s of these things banked already. I saw datto had like 6K shards and 1K cores. Plebs like me dont.
