So,

I am newly addicted to LS and spent all my FG so far on this guy

Could you check out my toon, in profile and let me know what I should upgrade first, and include stats and specifics. I am just now finding it hard to keep up with tanking/healing in groups.

Also, when do the good items start dropping that I can start selling and investing in this guy. I have only lost fg since starting.

You need to upgrade your Heal Charm to a level 55 as soon as you can.

Guardians need to focus on healing, so you should also look for some items with Heal Mastery on clubs, chain or plates, and heal charms.

You can find a good drop at pretty much any level from 10+. You simply have to get lucky

Awesome, thanks for the hints,

So basically anything with 100+ ee is pretty worth keeping?

Then, THings with good +'s in Vit Dex Int and Str?

Here is a decent guide to what items to keep. Ignore the second post, as that is not how muting works anymore and is thus invalid.

Also check the trading forums, some people are looking for specific tier/magical levels for muting/glyphing vs. 1fg each.
