Not offhand, but there's not a terribly good reason to have more than one char (you can respec literally at will at no cost outside of combat, there's even a mechanic to store your favorite specs with their gear so you don't have to look through your bags to find it), and no reason to have more than three (which is default character slots), if you want to see the full assortment of storyline missions for each secret society.
I can think of a few marginal reasons. Family members sharing an account is one. I sometimes have characters that I level up only with other players. For instance in Diablo 3 I have a Demon Hunter that I only ever play once a week with my brother, and he has a Monk saved for the same purpose. I liked the character enough to make a separate Demon Hunter for solo play, but I keep that first character exclusively for coop so that we're always on the same level. Marginal reasons, sure, but there's even less reason to restrict players like that. There would be virtually no extra expense for Funcom to increase the limit. With how you say there being very little reason to have more than three slots, the additional slots in the cash shop aren't exactly going to be a hot sale. If there are any prospective players out there that see this as shady and are put off, then is it really a wise decision by Funcom?
