Wholeheartedly agree with WillRiker.
It seems the arguments against it are kind of along the lines "it was a hassle getting all the gear together and macroing it in" & "it breaks realism"
As for it being a hassle, I hear all the time people complaining how easy the game is and how they want more of a challenge. Tailoring individual sets of gear for your job for specific situations brings much more of a challenge, and richness to character progression.
Ok, it breaks realism but seriously if someone's complaining about that its just because they've run out of other things to complain about.
Gear swaps definitely means players will be looking for a huge amount more gear = more content, more work for crafters, more NM camps etc
