Hopefully Bungie adds a matchmaking Raid tier, ala LFR from World of Warcraft, and people like me will be interested.
Going from casual, soloable content to Hardcore, High Item Threshold, Friends-List-only Raids with literally NOTHING in between is a flashback to the "HITTING THE WALL" that turned people off to WoW back in the day (and Everquest for that matter).
You can't leave casual fans with nothing to do at level 26. The age-old MMO mistake of making content that only 10% of the playerbase will ever experience should not be repeated.
Blizzard learned and adjusted. Hopefully Bungie will too.
