I don't see any feature or product(item) that we could use to be able to reset our life skills levels. A feature like this would be cool.
Like for instance you have spent your guild points on upgrades too much for cooking but would have liked to use them on Alchemy instead(as an example).
I would love this, because it would beat the alternative(creating a new character and doing it the way I want from the start, wasting all my hard playing hours/days/weeks/months etc).
An item(or button) that cost a certain amount of Coins(or Ingots) that would enable you to reset your life skills levels would be nice.
