D2 players who did not purchase Foresaken have no access to Spider to purchase "enhancement" cores. Since the enhancement core economy applies to them as well, a necessary source of enhancement cores is unavailable until they also purchase the DLC. This unequal treatment is classic pay-to-play. I can understand (but disagree) with your decision to include enhancement cores in infusion, but the Spider paywall is manipulative and inequitable to non-Forsaken players. Bungie must make Spider available to all players since the enhancement economy applies to all players. I hope the dev team is listening.
