I hope SE is planning to get rid of cross class
I like to play tanks and healers. In the process of playing tanks and healers, I've had to level up many jobs that I don't like to play. This is because of the cross class system.
To play the job that I'd like to play, it's required, in every instance, to level up something else. It's not as terrible as having to level them to 60, but nonetheless, it's something I would not otherwise choose to do.
Please get rid of cross class skills. Take all those mandatory cross class skills and stick them in some other pot. It's already a testament to the poor implementation of the cross class system that it's only relevance is in 1 or 2 skills per job. What's more is that these skills do not vary much within each role (swiftcast, provoke, blood for blood, raging strikes, internal release). You have every class of a specific role leveling other classes for the sake of grabbing from this tiny pool of skills. Just stop it.
