This is true, but being able to stop a TAG or HI in its tracks during a rampage is VERY valuable. If the target is IMM-1, they can't react to further attacks until they reset, meaning it becomes easier and safer to remove them from the board. I don't see it as being quite as useful against hackers, but it can also be used on remotes, and remember, G: servant bots are REMs, and are hackable. Being able to shut down that little helper bot in ARO when it's on its way to repair a busted TR REM or heal up a downed trooper can be really useful.
