Personally I'm pretty much set on Sylvari Guardian, Norn are too big for my taste, Charr looks a little too ferocious, which isn't very guardian'ish, in my opinion, Asura are too small and more castery and human is just too ordinary. Of course it can change, once I see the finalized Racial Abilities, there might be some amongst them to change my mind.
I'm (like most others) going to be using Sword/shield and a greatsword for off-choice, for the very reason someone else mentioned, the leap looks AWESOME! But again, it might change when I see the finalized skills
