Funny you should say that. I think Radio Silence (at least the idea behind it) is actually a hidden gem as one of the very few abilities that expands the strategy of the game beyond brute force, and I think it's a shame there aren't many more units or abilities like it in CoH2. I would've loved more "spy" units and abilities (like vCoH's PE Vampire HT or the Commandos radio triangulation) that would have let players fight enemies in more ways than bullets and shells.
My problem with Radio Silence is it messes with the
user interface, which is an absolute no of game design for me. A good UI is a intuitive interface you forget is there, and having abilities mess it up shows a deep misunderstanding of what the UI is for.
Similarly, abilities designed solely to stress out and frustrate the opponent fly in the face of designing a game that's fun to play.
I don't think Radio Silence is like the Vampire HT or Radio Triangulation at all. I'd lump it in with abilities that randomise the opponent's hotkeys for 30 seconds.
