I think you should look for alternatives in the game and not be modifying the skills.
for the developers, just as they are leaving the magician's ap as if they were paper, they should leave as is the warrior's footprint.
Today a human wizard sent me a letter saying that because my party had 3 priests. I look for solutions, like when they play with cube magicians we do not say anything and we look for solutions.
what Krischeriko says is true. Few use mino, lego, scorpion shield, anything anti-magician. I see that all warriors use full ap.
In what I should observe is in the stun of the magician, the probability of stun is high.
This will help the market not to continue to fall in price.
It's just my humble comment.
