I'm probably about as casual as you can get. For me, I don't have a problem with the difficulty level, because I know it can be beaten. It might take more effort on my part to find that perfect group, or pull from my FC, but knowing that someone at least cleared the content gives me hope that maybe I too will someday clear that same content.

I know it is difficult for some to find 7 other people who have the skill, or at least care enough to learn through failure. I have yet to grow a pair big enough to try any Coil 1 or Garuda EX (I have both unlocked), but I know that the mechanics might prove to be a challenge, but not impossible as long as we all try.
