I didn't realize there was so much dislike... the weapons are crap, though. Never used a single one except for the machine gun, and mostly because of the cocoon perk. For KF, I was also lucky. I fell into a great raid team, and we ran that sucker quite a bit. KF also saw the intro to challenge modes, which was cool. I thought the challenge modes weren't all that challenging, though. Golgy was the most difficult out of the 3, and that was cake if you had 6 people that knew the strat. I find WotM (Aksis), to be much more difficult, but I've also scaled back my playtime these days. The challenge modes (more Aksis) are WAY more challenging that KF. You can also get bogged down at Oryx. Oryx was more of a "you either get it or you don't" type of encounter. It took a good couple weeks for me to learn and get acclimated to that encounter. Also, unlike what some are saying, you can have one person die and still have a chance to make it through. It gets really frantic, but it's possible. IIRC, Crota was way buggier than KF.
