cross class skill pool

[SendohJin]

Then why did they make a system that still provides people the option to not have those important skills?

1) just because something is important doesn't mean it's always necessary. doctors are important, i haven't seen one this whole month.
2) because there's a segment of the playerbase that wants to customize so this is the bone that they get, even if it's the teeniest tiniest one they can find.
3) they want players to coordinate just a little bit more, hey if healer A has Protect, healer B can get something else.
