The one job only people? I'm pretty sure the reason for them changing the skill system is to do away with 2.0 content going forward. Besides the cross class system was so poorly implemented to start with you almost had to level up an entire class just for one skill to properly utilize your main class. All the classes should of already had access to all the skills they needed in order to function, it's mind boggling why they didn't do this with 3.0.
This is as well. This game does a horrible job presenting information, either it doesn't do it or it does it to little to late. I tried tooth and nail to get a friend of mine to play this game. He wanted to try all the classes out to find the area he preferred to play as, this was before the Novice Hall came out, and he didn't want to take up other people's time while he was learning the basics of each 3 classes. When Novice Hall came out I told him how they implemented it and he thought it was slap in the face to start what he calls "the training quests" when you already slogged through a few levels of the game with no mention of a guide that helps people.
