Job Tutorial for Legacy?

Just wondering, just popping up in the world with our Lv50 with all the abilities/skills having changed...

The new players can learn one skill at the time but how does it work when you start at lv50 and "begin" at your job with plethora of new skills?

Instead of just trying on field and getting pawned it could be nice to have a tutorial about changes made for each classes when we transition and a "training" where we could test skills without getting attacked or killed

I don't know... just an idea

Some skills will be gained through questing. So we will need to progress through quests to gain all abilities. It should be fine.
