Oh and another question:
In EQ2X I have a Shadowknight.
Love him. He's a tank, but he's also a decently well rounded class...
Would the Paragon be a good choice for me here? (I realize this is going to take some trial and error with classes, but I figured I'd ask)
You'll want to play around with the soul system a lot until you find something that suits your particular playstyle.
Paragon is a DPS (damage dealer) soul primarily, which means that its specialization points (called branch points) focus on making health bars go down. While it does have a lot of reactive stuff that happens when it parries things, its primary focus is to make the bad guys die.
If you're looking for a tank, what you're looking for are the souls that include "defensive soul" in the description, it'll be right at the top of the tooltip.
For warrior those are: Paladin, Warlord, Void Knight, Reaver
For rogue: Riftstalker
For cleric: Justicar
For mage: roll one of the others
If you're looking for a well-rounded soul in the warrior calling though, take a look at Riftblade. If you pair them with a couple of tank souls and stick a shield on them they're decently survivable and can handle most of the leveling content just fine.
Keep in mind also that you're able to have up to 4 roles, which are essentially additional configurations of your soul trees, not necessarily with the same three souls. So there's lots of room for experimentation.
