There is no problem with cores and progression in Destiny 2. It is literally a made up problem. Cores do not affect progression. Screaming loudly that they do doesn't make it less of a lie. Maybe, just maybe, the reason you haven't gotten what you wanted even after screaming about it for months is because your opinion doesn't match the opinion of the majority of the player base nor does it match the direction the developers want to take the game. Maybe, just maybe, we have all heard your complaining loud and clear, but you don't actually have a good argument nor a good opinion. Maybe, just maybe, forming a mob doesn't make your demands more credible or worthwhile. At this point, the fake argument and outrage over enhancement cores is bordering on social terrorism. Calm down. Play the game. Play a different game. Stop trying to threaten and scream down people who don't agree with you.
