FATEs get harder. Some involve some basic reasoning skills like "See a red circle on the ground? Red circle equals bad. It causes booboo, even permanent nappy time. What should you do when you see red circles on the ground? Stand in them? No." Otherwise, most NM FATEs are just slugfests, but there is some level of consideration for the mechanics, and you CAN die by pulling aggro but because you're spamming ONE skill, no one's healing. Or tanking. And Archers are trying to kite the boss away by doing this one-button spamming.
