Changing back Awakening skill to the old one

my good old dark form self-buff skill (orc racial, +20 fire p.atk) was deleted, when i have learnt tyrr skill rolling thunder at lvl 89.
i'd like to change it back to my old skill, because the new one seems useless for me.
how can i change it back? with ingame method, or with gm help?
help me please here, or in private message!

 

ist just lol, u should give the way to relearn that skills somehow, i rly dont understand it, u make ppl reroll a char just because they unlearn a skill.

best option would be, delete all 3rd class skills at awakening and delete all 3rd class skills for chars who are 85+ in the game. ist not supposed to be like that with old skills.

 

innova eu cannot do anything about it, they are bound to ru or the main kr branch thells them to do with these skills or not.

 

more profit for them. we have no guilty on your lack of knowledge, so no need to delete old skills bcuz u don't have.
