Hmm... Other than 1 Armor, -10% Attack Speed I'd guess that my last suggestion is actually the weakest incarnation of the Riot Shield suggested in this topic. Against anything but a Troll Slash it is barely as effective as a C2, which is generally seen as a trash item not worth the time to pick up. And that's considered too good. The 1 Armor, -10% Attack Speed really only plays into one tree that is available on one storyline. I don't much like it, for reasons stated time and time again in this topic. It's strictly worse than an item that is already viewed as worthless for the most part, C2 Armor, and takes up a Mod Slot that could be used by much more useful items on pretty much everyone but the Assault Tank. That said, a "Limit: 1 Stack" should probably apply to the Shield. Particularly if it ends up as something that ends up with more than just one spawn per game (I kinda laugh at the idea of a Protection Assault using 3 at once). But also if it actually ends up something a bit more useful in general than that.
