How is it "more user friendly"?
It's not user friendly at all. You're thinking of the Optimal Rank system which tried to accommodate freedom of playstyle but still managed to suggest "the ideal way of playing".
How many mages did you ever actually see in full plate?
Personally, I'd admire the spectacle, but quite frankly didn't see it happen too often. Namely because most mages realised that gear severely gimped them.
Anyways, I have always had over 5 gear sets in my inventory. It's not a problem for me carrying around so much gear. What's annoying is that I can not casually wear what I want when I want, despite having earnt the right to wear it, and also having earnt the gil to buy it. There is a huge heavy-handedness guiding my every move in this game now, even when all I want to do is:
- Not be naked every time i attach materia for someone
- Not have to reaffix an entire wardrobe just to do a few low rank crafts every now and then
- Have the freedom to customise gear sets in line with the Armory System
- Have options for wardrobe
- Be able to buy stuff on wards a few ranks above me and "grow into it" instead of using my R1 item until lvl 18
