Guild Wars 2

First post here and a big hello to all of you on the forums.

I currently have a Lv38 Human Guardian running Scepter/Torch and Staff.
As far as weapon and armor stats, I’ve gone with Precision and Condition Damage for crits and more damage on burn. So far, it’s working out decently, minus the fact that I’m deathly squishy when it comes to fighting Champions.

So, as the title states, I’m hoping to gather some advice on whether my current setup is a nod to the correct direction or if I should go and switch out to a completely new stat build altogether if I am to survive in the higher level zones. Also, any kind of insight on Guardians and Condition Damage would be highly appreciated, as I love setting things on fire.

And finally, what would be a good investment of my Karma points? Currently, I have a little over 10k Karma points and I am unsure to either keep saving up for an armor set from the Cultural Armor Smiths or if I should just invest in a weapon at Lv40 or so.

Thanks in advance for your time everyone!
