This might depend on what the sylvari look like, as a pen&paper player I do tend to play old race's such as Elf's, halfling's, Gnome's Dwarf's, Pixie's (for Lol factor and and no one really expect's that a tiny creature can end up backstabing you if you insulted her :P).
My list might look something like this.
-Human male Guardian (most likely with sword and shield to resemble my demi-god Paladin which was my first introduction to dnd)
-Sylvari Male/Female Assassin (if the Sylvari don't really resemble anything like an Elf then it will a Norn Assassin
-Char male Ele, most likely focus on water since well i like blue animations, and chilling hot heads down.
