I don't know if anyone's brought this up for AC3 yet. Having default sets so that new players aren't screwed is a great idea, but it was poorly implemented in AC:R. Once you level up and grow beyond the need to use the default sets, they just sit there like a tumor, getting in the way of your other sets when you're trying to flip through them after being killed. It would be a great improvement, I think, if you could overwrite or delete them after a certain level. Maybe even after level 50, I dunno. I'd just like to have the option to get rid of them after a certain point. Or even 'hide' them, making them inaccessible until you toggle a 'Default Profile Set' option somewhere or something.
