Building up on the idea, other MMO's also show previews of the combat as said job

For example in Black desert you get small video previews of the rotation once everything is unlocked. I believe XIV could have this in the creation screen too, with PLD using confiteor and shelltron, Warrior using inner release and upheaval, etc. Just a small preview of what the job looks in action

Definetly support the roles clarification, a very nice QoL for new players
