If anything, I wish baskets were lower so that people could be more aggressive from longer distances, one of the most exciting parts of our sport. You'd also have the chance for more skip shots holing out, and holing out rollers in places that receive significant snow in winter.
We could take that a step further and make sure every basket has a back-stop 10 ft. behind it so that every putt could be run hard without any concern at all about three-putting.
The threat of the three-putt provides much of the drama in ball golf on TV. When an aggressive 20 footer to win lips out and rolls 5 feet away, everyone feels the the player's dread of that come-backer to force the play-off.
Par 4's and 5's have finally been accepted by the masses in disc golf and are being incorporated into more and more new course designs. To complete our break-away from the deuce-or-die mentality we need to make the three-putt a much more common threat.
