Since they make it so easy for anyone to hit LVL 31 now there is an abundance of players who aren't very good. I've noticed this trend when they came out with the expansion. I almost always use LFG and it seems like nobody knows what they are doing. It's more prevalent in hard raids that require a better understanding of each guardian's role. Weird how all you ever see are hunters but when it comes time to find one for Hard Crota you can't. It's because so many of them are frauds who don't get how to do anything but go invis but even that they can't do for Crota fight because it entails more than just kneeling. I had deleted my 30 hunter an 30 warlock but recently started them again as I know at least I can provide that role once I get them leveled up.
