Re-rolling from Warrior, thoughts?

Stuns don't work on ADS. If you're asking a monk to use Arm of the Destroyer instead of Bootshine or Dragon Kick on a single target then your group composition is wrong, because 130 TP for a 1s silence is the least possible efficient way to deal with that situation. That leaves Bards and Paladins, so you better have two bards for ADS if you don't think the PLD should be silencing.

A 1 second silence is essentially an interuppt. It's not intended to blanket shutdown the enemies, you're timing it to coincide with skill activation so their spell breaks. Between invigorate and bard song a pair of monks timing their rotations to be half a cycle out from each other and replacing bootshine with arm of the destroyer in their rotation could effectively shut down an entire group's spellcasting for a very significant duration (~a minute or more). It's arguable if their DPS would even take a hit if they're hitting multiple opponents the net HP lost from the enemy force is comparable to the focused DPS of bootshine (Threat may become an issue however)

A 1s, 130 TP, stance dependent silence that is never worth using on one target unless you're soloing and can't use Steel Peakt. If you HAVE to use a Monk for silencing it's a good move, but if you have a Paladin and a Bard you should never ask your Monk to silence anything, especially not ADS.

And "an entire group of casters" is not a single target. ADS is a single target. If you have three or more targets you should be hitting, then you should be using Arm regardless of the Silence. Like I said, if you HAVE to use the Monk for silencing its good, but if you don't have to you shouldn't, because it is not as on-demand as the PLD and Bard silences. They have to sit in a single stance to get the silence if they're not perfectly synced with High Voltage. I mean, Arm definitely has its uses, but I guarantee that if you are making ADS one of those you're doing it wrong. They can be a backup, but by the time you realize someone missed their silence it's generally too late to use Arm unless you were sitting in stance waiting. High Voltage isn't really a long cast.
