Hall of Novice lesson for role utilities.

I don't know if this has been posted or not I tried searching and didn't find a post about it so if I missed it I apologize.
I am suggesting something like Hall of Novice lesson for the basics of utilities.

I know there are more in-depth videos for this (thank you so much content creators that make these guides they have helped me a lot I am not trying to put out of the job with this suggestion I promise.)

Mostly I am talking about just basic role abilities.

I would love for more players to feel comfortable doing their role and not stress about if they are being a good tank/healer/dps.

Specifically I feel things like that stop some people from wanting to try tanking or healing.

Also it's bad if a person decides to go with GNB (myself) as their first tank I learned that was a bad idea, the hard way :o.

As a returning player I recently made a new character and realized now (after all this time because I am ignorant sometimes) that Hall of Novice does not have any lesson that teaches players how/when they should use role abilities.

Rampart/Swiftcast/Second Wind and interject etc. (I had to hear it from someone else before I learned that interject only works on enemy cast abilities that flash red.)

I think this would help new or returning players get more comfortable with roles they have never played before.

TLDR: Hall of Novice basic role utility lesson. Also forgive the bad grammar if there is any
