Why people are complaining about this awesome change. For what I saw the majority of cross role skills are really good (in all roles) so you gonna need to make some decisions.

For example, in 8 man content do you need an esuna? All tanks should equip a low blow stun (they have no damage btw)? Only 1 healer need protect spell. Cleric stance for more damage or a safer option?

It feels almost like a skill tree that ou can change it anytime.
