Apparently there are some rumors circulating about level boosting microtransactions in Destiny that were added but currently unavailable as well.

I don't mind FFXIV's shop selling old seasonal items as those are all just glamour that could have been obtained in game easily by anyone who was subbed at the time. Unique items, especially the dyes that are one time use, are a lot more irksome and to me have no place in a sub model.

The only game I can think of that does a cash shop right is Path of Exile. Free to play and from the cash shop you can purchase additional bank slots (one time purchase), though it's mostly unnecessary unless you like to hoard/ play several characters (shared bank). Everything else is just a cosmetic effect, either alternate skill animations, pets that follow you around doing nothing (minions), wings, halos, and the like.
