Well, I agree that there needs to be a limit, but there is a point where it goes too far. I dig the idea of using all your own picks to go over the limit. I'd be even ok with being able to upgrade them to the limit (or 1 under) with other picks then go over with your own picks (Over by 3 max.), or you have to spend +2 of others picks for a +1... just to prevent wasted picks. I'm still sitting on a +1 that no one seems to want.
I literally ended with +9 and just deleted them because I don't want anything for them
