The answer is simple, yes raid is hard, yes it takes planning and teamwork, but nowhere does it say you need to have a dedicated no life band of guardians willing to raid on whim. Bungie has stated many times that this game was created for the casual gamer first, yes there will be challenges, but Bungie has no plans to lock out the casual player base. Imagine logging in with three friends, looking for two ore and being set up in matchmaking, before the mission you can talk to each other and a sign roles, just like many people did between instances in WOW... Now you have the ability to just log in and be put with a group that needs you, and friends who have enough to fill the roster will work even better together. But the difficulty will stay the same, and eventually someone failing the mission 20 times will learn how to run it with a randomness team and perhaps even take on a leader role. Besides in destiny, there's not much distinction to lean on one class more than another for a.specific situation, such as best at AOE, someone to pull aggro, or a healer, etc. Everyone is just awesome and shoots stuff, using ults wisely and etc. So I don't see other than playing with a total deep would make a.mission any more easy than.playing with a bunch of well organized buddies. Easier yes, but impossible without, no. I also imagine they will be matching teams by skill level perhaps a ranking system, to help weed out those not as serious and match higher ranked players with others who they will most likely not have to carry. So in case you didn't hear before, Destiny is first and foremost a.casual game, you don't like it go back to WOW or etc.
