Hmm, as far as the cons go. The money that you save buying resale more than makes up for the loss of the pass discounts. Some have done the math and found that it would take decades to break even on that, and some never would on the 2042 contracts. You can still buy the passes on your own, and then get the majority of the discounts that DVC members get anyway. Yes, you do lose certain perks, and you don't get all of the discounts that DVC offers, so each individual person has to make the decision on whether those perks/discounts are worth the extra price for buying direct.
Oh, and just don't go there in the summer. Early spring, late fall, and early winter are not too bad at all.
