Trust was a terrible idea in the first place, because they couldn't even be bothered to make it as good as the XI system they already had in place. In the effort of making an MMO cater to solo players, which, to be honest, is its own problem, they screwed over their story, because now we have to have 7 other NPCs suddenly appear. They had to neuter older dungeons because the AI couldn't handle them. And on top of all of those terrible decisions, still don't let players use them for all the content, which defeats the point in creating the system in the first place.

And I'm not even talking about Savages, or Extremes here. You cannot complete the MSQ with full trust, because the final trials never let you do them alone. So what was even the point?
