I understand the possible negatives for having a matchmaking but....it's only an option to use. You can still do LFG and make your own fire team. I can't see how having an option that allows single players an easier time to access content is a bad thing. I don't raid at all because it took a few days of trying around 2-3 hours each day on LFG for vault of glass and then the same for kings fall. I don't want to have to spend hours trying to find people so I can go do that.
