This would be kind of broken. This ability would negate other classes abilities. It would be like fighting without a sword ability. In Champions or Clans, sword abilities are usually the most useful. A brute without flesh hook, a knight without hilt smash, a mage without lorb or ice prison, a ranger without a bow, a sin without evade. With 1 ability it negates all other abilities, and this isn't like silencing arrow, since silencing arrow you can use a water bottle.
