As far as XI, which job was in highest regard was completely situational. Of course, people are going to gravitate toward the more efficient, but by no means are people going to completely deny any job who is worth their salt at what they do.
As a leader, I never looked at any job and went "Eww. No." I even preferred SMN > BRD on Imps and DRK > SAM in the same situation.
In fact, I fully believe that the majority are too lazy, which is my point entirely.
