The main scenario from 2.0 to 2.55 really is not that long, especially skipping the CS's. Its just a few hours worth of quests and go through two dungeons and two trials that are both stupid easy to beat. I don't recommend skipping CS's, but the hurdle from 2.0 to 2.55 does not take long at all and the MSQ are enjoyable to watch. If you get worked up easily to this, then you likely would of found some other excuse to quit down the road.
