I understand that you don't want to bog it down with "heavy graphics", a few well placed graphics would do wonders for your site. Also, because it is World of Warcraft related, I'd recommend a darker template. Try to give it a color scheme similar to worldofwarcraft.com
If anyone's looking for WoW specific news, I'm sure they've been to worldofwarcraft.com, so it makes the association of those colors to WoW in the user's mind.
That's my two cents. Good Luck!
