In the stress test I made a Dwarf Warrior and a Orc Hunter. Both were pretty fun. When the full game is released I plan on going with a Troll Warrior on one of the PvP servers. Most likely the PvP server nearest to the bottom of the server list cause I figure it will be less populated than the first few on the list. I enjoyed the Warrior skills, charge was pretty cool, and I liked the ability to tank monsters 3 levels higher than me. Didnt notice this as much until I made the hunter and died to crap 2 levels higher than me.
The Hunter class' Pets are broken, and shitty right now, so they're not quite as good currently as they will be. Personally, I liked my Tauren Hunter a lot. My Undead Rogue wasn't half bad either.
