I'm not sure how much more difficult development-wise it would be to make Silence function the way it theoretically should, but it would be nice if it did more than just stop spellcasting. For example: In the goblin camp, I lured Gut into her side room to assassinate her without alerting the whole fort. After attacking her to start combat I rolled a pretty poor initiative and was certain I couldn't kill her before her turn, so I dropped a Silence on top of her to stop her from yelling for help. Instead, she stood right in the middle of it and called out to the guards, and the whole place was alerted.
There's also another section near the druid camp where you can fight a few harpies, and it didn't seem like Silence worked there to stop their song either. It'd be really cool if stuff like that actually worked.
