Functional, but not necessarily as handy to some generations who don't use Twitter. ;-p
Generally it's easier for less-saavy (or "older" if you prefer) users to go for an actual domain name.
(Myself, for example, could memorize that. But I must admit that being from an earlier time in the internet's birth, and not being a Twitter user, I use TinyURL out of habit.)
And if there is something I found most fascinating about the CoX player base is that there is a much larger "adult" crowd than any other MMO I've been exposed to, and who are not necessarily hardcore gamers or super-saavy.
Be that as it may, these printed pieces should start using the Bitly shortened version over that long word-soup URL, if only to save people's wrists who are writing it down; and also make the layout of the materials alot easier.
