Considering that the starting area in RO has access to all the first job class starts in one building you won’t see classes splitting up to go their separate ways in that game anymore. Not till 2nd job. Considering that the general level grinding areas are all basically universal bar a couple of classes.
Actually, the tutorial area changed a lot from what I remember it last. Used to be the garden had all of the mobs for the novice quests and all of the trainers. You would go and talk to some NPCs before entering the Garden which would explain the non combat side of things, then you enter the garden and you could talk to the trainers and even try the class out a bit before you commit to it. Those trainers would also direct you to the area you need to go to for your job change when you were ready.
All the stuff combat related in one small zone, sure you had to compete with other newbies for mob kills but the entire tutorial was done in only a few minutes because of how compressed it was.
And honestly if this is supposed to be a social MMO… why do you want to force everyone to start split up right off the bat? Splitting people up right off the bat, especially when we know that megas will not be so cheap when the game gets rolling, would only lead to people thinking that there is not enough population for the game and feeling very empty. Causing them to leave.
People should be splitting up after they have found a party when they got numerous fields or dungeons they have access to so they can farm the mobs they are most effective against. Branching out from the hub city.
Hell if they wanted to they could put class masters with special skills locked behind challenges hidden in places suiting the class itself scattered around the world, can even have unique attributes you can only get from those masters. Yet still keep the class trainers who get you started in a centralized area so that newbies are not being forced to split up from people who could help them.
