As the title says, a level 1 character can skill a profession to level 300.
There's an army of level 3 characters who make cured rugged hides, essence of water and arcanite which results in a flood of them and mass damping.
Return the level requirements + delete their professions?
To make it clear, no level requirement is a bug. On vanilla and tbc there definitely were level requirements for artisan, etc. level 20, 35 in vanilla and level 50 in tbc.
