I have never seen this happen before, so I guess when I come across it I wont be as shocked. To each his own, but especially with all the easy humidification devices it seems unnecessary. If it cracked so bad and was too dry I would honestly just throw it out unless it was some crazy rare smoke. Guess I have just had good luck with cigars at the right humidity.
It really has nothing to do how you store your cigars and more with the time and place you are going to smoke it.
Take a cigar stored at 70°F/70% Rh outside in 20°F and > 30% Rh weather and try to smoke it. It will explode on you if you don't first moisturize the wrapper. Regardless of how you do it, it just makes perfect sense in some conditions.
