I've noticed this with a some of my sticks as well. I keep my humi between 70-73% and with some I notice some restriction to the draw, (I've always chalked it up to how the cigar deals with certain levels of humidity). I also have a small desk-top humidor that I do not maintian the the RH in, that hovers around 60% on its own. Typically at the beginning of the week, I'll pull out a few cigars and place in there. Then when I smoke them throughout the week they smoke much better, (smoother draw). I have not noticed any loss of flavor but I would imagine they would lose some if they were allowed to remain in that environment for an extended period of time.
