Most players enjoy the speacialization of having a choice between knight and crusader in RO1 and the evolution of class as a transclass and 3rd class after. It would be good to know if there are plans to make specialization inside classes like classes 2-2 and transclasses / 3rd classes.
I can't see me playing the game right now, but if there were translcasses *-*
Probably in the future plans but as far as know its nowhere near there yet. The only similar thing we have is the level expansion which after getting to lvl 50 you will do a quest to upgrade into a Master Level Class. Right now the cap is only until Master lvl 20 but in a few weeks its gonna extend until Master lvl 30.
I also would like the idea of having transcended classes but the state of the game right now its pretty unlikely to happen soon since a lot of things needed to be fixed before talking about more content.
