I like the idea, but:
1) Why engineers should get 'advanced' tutorial and other classes not? (I have my theories but I wonder what your response will be)
2) Why is it important anyway since dumb players don't do tutorials anyway and smart players will learn quickly from vets and/or guides on forum and videos on youtube*?
3) Muse has been telling us that they have some tutorial rework going, we don't know how new tutorials are going to work.
*Paradox has this case that there is very bad tutorial for CK II but nobody gives a shit because everyone learns from Arumba's videos. I know this is a multiplayer game, but still.
