As best I can tell, she was saying what I said about it leading to what I identified as industrialized laziness.

I suppose part of the issue would be optimization. People will ultimately go to whatever gets them the best results. The devs have a hard enough time balancing the jobs without almost doubling what they need to keep track of balance wise. If one class or job serves better at their designated role than it's equivalent, players and statics will turn to them. Your idea Isn't bad on it's own merits, I assume that your Proposed system would work well on it's own, without the Jobs and with bosses designed to best make the best of it. But as it stands, Either your classes would superceed the Jobs, You'bring them up to second class status, or it'd be a case of the fist option for some and the second for others
