I really enjoyed the class system of v1, but since ARR it sucks big time. Now, it's a mere step leading to jobs.
I find it a shame that the dev had the audacity to demolish working systems of v1 like that.

However, if it's the decision they've diced to take, better get rid of it than leaving it as it is now -- a disappointing reminder of something better.

Furthermore, with the new zones being much larger than the current ones, I hope they'll also open up the current ones too. Removal of ALL invisible walls (except zone borders) is definitely needed.
May I request a tweak on jumping as well? It's currently a two speed jumping system, why not make it possible to have a directional jump from an standing position? It would help make small corrective jumps to access places more easily AND it's also more natural, fashionable, sexy, etc.

Finally, I hope that they add more complexity to the game (complexity doesn't mean more mindless grind!!).
