1. It is already optimal to use macros in this game, I don't see your point.
2. I fail to understand how the mechanic is dumb when it offers so much.
3. Elitism will exist whether gear swapping does or not.
4. how is the mechanic obtuse?
5. If you're trying to optimize you character now you have zero option in gear choice. There is and always will be a predefined optimal setup for every class/job.
