Well, I don't really like my proxies get angry when they activate one of my firemines... Or if i stick needle balls to a bot, and he hops straight into my proxy lair. Or if my turret damages one of them. Or, worse, 10 of them.
Proxys have always had a tendency to turn on thier masters... I don't think we'll be changing that. It's been a part of the Proxy for so long that it's become part of thier identity. If we changed it, the Proxy would be less... proxyish.
