NPC help is better than no experience at all, which is what players deal with currently. Sure, it's scripted, but then they at least have first-hand experience with things like Conflagration, Twisters, or Blighted Bouquet. Basically a version of "watch a guide" for those who learn better by doing than by watching.
As for forming a group and learning... easier said than done. Finding seven saints willing to sacrifice precious time on wipe after wipe is harder than any fight in the game. Personally I make a point to try and get content done within a few days of release, barring second and third coil as I was in the midst of a move at the time and so I've just accepted that I won't clear it. But I do try to help others when I have the time, and listen to the shouts in Mor Dhona. It's rare for them to go anywhere.
