Cores aren't even the issue. They are just a symptom. The real issue is that Bungie can not figure out how to properly reward time investment in this game. Starting over every season (essentially) wouldn't be such an issue if the unbearable grind set up by the randomness of meaningful rewards and throttled progression weren't there. Do you know why everyone hated the Ikelos nerf? It's not because we can't understand the gun was OP and would eventually need some kind of nerf to make way for other things. It's because it took some people hundreds of runs over multiple months to get the weapon (and that isn't including the many people who had to [b]wait[/b] until maxing in Forsaken to even attempt EP so their glory was even shorter lived). When you drag your player base through the mud to get a rewards (or make progression), they are going to expect it to last forever. That's why we can't start over each season and why people hang on to the weapons it took them forever to get. That's why everyone gets burned out doing the same exact milestones we've done for 6 months now. Until they fix progression, the game will always have these kinds of issues popping up.
