This isn't in the wishlist because I'm not sure about it, and I'd like to hear others' opinions.
So, Talad doesn't like the idea of classes. He says they are constraining. I agree with that, but I think they could still be incorporated into the game. Right now, training skills is nebulous. You aren't sure which skills you should have for the character you want. You aren't sure which NPCs to train with. There are no official trainers (they are mostly guards?) and no official gyms/dojos/etc. to train in. For a society that places so much importance on combat, the neglect of organized martial arts is unbelievable.
I suggest that we do have classes. There should be schools for classes, similar to how players have to go through quests to achieve Way mastery, but more organized. Maybe with a physical school, even, where trainers can be found and players can practice (rank up) with other students and dummies. I think it would make training combat easier and reflect reality more closely.
The school could offer many different skills. And that's when you choose your future skillset (class). You could ask an NPC about the classes, and he/she would tell you their specialties, which you could then focus on to become a master in that class. It would be interesting if NPCs could detect the ratio of your skills (if they were high enough) and then address you by that title. Like "Good day, Nostromo the Battlemage!" (Sounds dorky, but people like being special.) Of course, you'd have to account for the differences between classes so you could correctly identify a character. A spellsword is not the same as a battlemage. An archer is not always a ranger. And it would be strange if you had a character with a Sword rank of 180 and an Axe level of 150, and although he consistently used both he was always determined to be a swordsman by NPCs. So I think it would be simpler to have a trainer NPC ask a player, "What is your specialty?" and the player could choose, then leave it as that until he wished to change it. All NPCs would then address the player as the chosen class (given the player was qualified).
Also, not all schools would have to be combat-oriented. Just as there are cooking schools, music schools, and even colleges in the real world. I couldn't believe Aleena was offering herbalism training when it was implemented. It's so out of character.
I know this seems complicated, but I think it would be great for immersion. And I think new players would appreciate it, as it would help guide their training. Personally, I think players who have mastered skills (at rank 200) should be able to offer apprenticeship to lower level players, but somehow I doubt the developers would like that. So I came up with something completely different.
