Um, no. It's that way because players were just leveling up the new jobs, PPL tend to dislike extra responsibility/effort (tank & Healers), Gunblades, and two of the healers were severely nerfed and the removal of protect making healing in early dungeon into stone vigil levels of benefic II spam, which when combined with the introduction of trusts: drastically lowered the number of healers in the duty finder.
I literally had a tank that just abandoned the duty after seeing my AST job symbol in the party list, like, two or three weeks ago...
