Ok, this subject only takes a google search to see hundreds of people in various different forums asking for a profession reset to be implemented to forgive previous mistakes new players had made.
Now i understand that the devs do not want people to abuse the system by freely changing profs fully depending on what they need to be for certain tasks, however there are a couple of ideas that could help counter these worries.
My first idea would be a buyable 'memory potion' from diagon alley for around £9.99 with a cooldown of 365days much like the faction change medallion in pogo, this not only helps players that want to fully min max a profession after making a few mistakes but it also stops the system being abused.
The second idea would be able to fully reset a whole profession but only be able to use the refunded items into the same profession again, but there also being an option to exchange scrolls and books in one profession for some universal ones to be used anywhere at a ratio of your choosing, ie 3 scrolls to 1 scroll etc etc.
Thanks to the devs for reading this and letting the community have our say!!
