seriously.....getting people together to do old content is a hassle.....a really bad hassle. Its bad enough some people have completely forgotten what to do but..........just take the catalysts out of there. It was a horrible idea to put them in there to begin with.
Faction Catalysts will become available in the summer - we'll have more details on sources closer to the date. As for the Raid catalysts, I'll pass this feedback along to the team.
