Are role actions a nerf?

Because having all 10 would be overpowered?

We've been used to having all the good cross-class skills since 2.0 because for a majority of Jobs they only had 5 viable Cross-Class skills, sometimes less! BLM is an example of this. Even though we have access to 7 cross-classes, we only have 4 good ones. Hawk's Eye is useless, ruin is useless, and Physick is also useless but still has an extremely niche use.

We just have to adjust to not being able to have all the good cross-class skills at once.

EDIT: Besides, having all 10 at once defeats the purpose of the system in which WE'RE SUPPOSED TO CHOOSE.
