My honest opinion on this is that I feel that the devs want to make jobs feel unique. I agree, the ability of annoying but I lean more toward the idea that people need to communicate with their team to use it properly which isn't that hard. This is an MMO and the idea is that you communicate with your team.

The devs seem to want to make it a high risk, high reward skill which in some way thrilling. YoshiP said it was because of "job identity". I kinda side with the devs on this one.
