My main is a Orc Dragonknight with a Great Axe and Heavy Armor.
(Based him off a D&D character).

I have a secondary High Elf Mage, but didn't get far.
Too squishy and the attacks take too long, causes you to run around too much which only attracts even more enemies.

I contemplated trying the other two classes.
But I'm no good at buffing/healing (nor do I think I'd get any use from it. Considering how I have no to really play it with who actually wants to play it).
And stealth... in combination of other's stealing kills and from what I heard with it eating stamina... It just seems really bad. :/

I am tempted to try a Nord Great Sword Light or Medium Armor though before the Beta ends.
The extra speed and agility over the Orc would be fun to play with.
