Barbarian magic suppression skills...

I am a proponent of relying 100% on the effects of skills. That is, I only take a skill if I am absolutely sure how it will help me. For example, if I take Luck, it will help me in every battle. But if I take one of the Silence skills, it's not even certain that it will be useful at all. And of course, I agree with the others that even if you guess correctly with the Silence skill, there are still skills that offer much greater benefit in battle (like Luck or Morale). And I have never seen an opponent use only one type of magic in battle (at least 2), which means that for real benefit, you need to take all 4 Silence skills, and that is an unaffordable luxury. Conclusion: Silence skills are nonsense, poorly designed.
