Small problem with this - moving the knockdown to any tier is a quick way to make it even easier for Magic Gunners to knock people to the ground every other turn. If Silence was added as a High Charge effect, I say the knockdown would have to be removed entirely.

I will note, though - people did complain about silence. I couldn't tell you how many, but they absolutely did.

Sonic Shell was pretty oppressive against anyone that tried to do a purely magic reliant build, and even some of the less magic reliant builds would regularly have a manageable situation become an impossible one because someone had an on-demand 3 momentum Silence move that can't fail outside of a mage somehow successfully dodging a person that has 300+ hit, potentially multiple times in a row. Even if it's a wind mage with Blind, most mages will have a hard time doing that, especially if the Magic Gunner uses Overcharge. Easy ways to disable all spells is why things like Silent Prayer and Whispering Cant were even created, and while those are there, that doesn't account for other magic classes like Tactician or Ranger. You can use a Screaming Tome or a Heron Feather, but the Heron Feather requires an accessory slot and didn't even remotely stop some forms of silence, while the Screaming Tome either requires you to use two weapons at once or instead switch to the Screaming Tome, activate Screamer and then switch back. A full turn and/or some HP, just to be able to do something again.

Freely accessible silence isn't really a good thing to have, as things go, unless silence itself is changed or they were made difficult to use. Perhaps disabling some number of random spells would work better for this in particular?
