But there is something preventing me from having an actual, functioning toolkit from the beginning if the job starts at level 1 - which is excatly that: Starting at level 1!
The last two expansions were clever enough to give us jobs that were already at a functional level, with a functional toolkit. You're telling me just to do content that I might not enjoy to get the job to an enjoyable level? I want to enjoy my leveling experience and thats much, much easier when it doesnt start out with an aweful dread through stuff thats not very intresting (FATEs, killing low level enemies by hitting one button in whatever scenario) with a job thats not very intresting (hitting one button - and btw that teaches me nothing about the syngery and the gameplay of said job)
On the other hand there is nothing stopping you from pretending you dont have a full toolkit and going through the dungeons in order - if you really wanna do that.
And there should absolutly be nothing stopping you from helping your friends that you recommended the game to - for sure not your level.
Yes, a leveling experience is needed to learn a job in a more safe enviroment and by giving us more and more skills over time - but frankly: The first 50 levels add little to that, at best they do nothing, at worst they confuse or teach wrong things.
If you really want to start at level 1 - you can do that in PotD just as much as I can start at level 60 there...
...and saying that I'd like to repeat that I dont even mind an option for players to forcefully delevel and start at 1, if they really desire to. But dont make me do that. Dont make me go through low level FATEs or PotD again (some of the stuff you listed wont work for levels 1-16 or even 16-50 - cant really do hunts at level 10, at least not most of them) when the devs already showed that they understood that giving us fully functional job at a certain level is the better way.
