I've played a TON of the different classes (Fighter, Rogue, Barbarian, Shielding Swordmage, Wizard, Psion (as a test), Ranger, Warden (my favorite so far), Avenger (my least favorite at the moment) and a few others in random pick up games. The only ones I have extensive playtime with are the Swordmage, the Rogue, the Warden, and the Avenger. I'm looking forward to the uber-stickiness that my Shifter Fighter will have (though he won't be the hit point power-house that Crag is, though he will hit harder, especially on opportunity attacks, lol) and I'm looking forward to trying a half-orc brutal rogue (only tried the artful dodger before). I'm willing to bet he'll die early, but he'll be taking at least a few down with him, lol.
