Did they change the way warriors work before level 20? I played a warrior a long time ago and got him to 18 but eventualyl deleted him. Ended up making another abit ago and got them to 18. The one that just hit 18 doesn't have Sunder Armor and I still only have 1 stance. I am pretty sure I had Defensive stance by 18 and at least 1 rank of Sunder armor. In fact I don't even see rank 1 of Sunder Armor on the trainer, I see rank 2 at lvl 22.
I passed up a couple of class quests but I just remember them giving junk rewards for a huge time sink.
