No. I tried it with a Gambit configuration and the game was boring as hell with them on. Then I turned them off and opted to control every character manually like I normally do in these games and it was suddenly a lot more enjoyable. I admit the wording in that post is extremely misleading.
Gambits make the game very dull; sure you can get a configuration that works but then doesn't that just mean you may as well put down the controller? Seriously, what is the point of setting up a bunch of things that make the game play itself? I can select my own Hastes, Cures and Firagas, that's what FF is all about for me.
I suppose what I'm trying to say is that if you weren't a lazy gamer (which unfortunately a lot of people seem to be) then there was no need for Gambits at all.
