A totem should represent the character, though not all do and sometimes poor totems are chosen. I don't know your character, but keep in mind that you should try to find something in nature that represents him. For example, my first druid was a very old man, nearing death. I appropriately chose the totem of Wilting to signify his age.
As for your question, dragon is the totem of a demi-aspect named Apollan, and as such, it is heavily frowned upon to reuse the totem out of respect for such an important figure. Look on the first page of this topic for all members and their totems. Any of those totems that you see shouldn't beused again until that druid is deemed lost.
As to Legocrazy, our Arch Druids are currently from three different timezones to attempt to encompass the greatest amount of players possible. I assume you are from the West Coast, and as such, I'd recommend that you try catching Leyun (Tristanm1) online. If you can't catch her, Elorna (Birdwhisperer) and Dalari (Friskyelectric) happen to be quite active. If all else fails, try to check if any hierophants are online and if they are, they should be more than willing to provide you with a lesson!
