Yuletide Nomination Dilemas

Having finally settled on my three precious fandoms, now I have to sort out the character nominations. The Mysterious Cities of Gold is easy, since there are only four characters I really care about, but the other two are proving a challenge.

I mean, choosing four characters from The Secret World, which has dozens of people I would be interested to hear more about? Torture!

I have decided that my third slot should go to Monster by Bigbang. But deciding how to nominate characters is tricky - should I just use the stage names of the band members? And given that there are only four slots, which one do I leave out?

Yuletide: why so difficult?
