I agree with kebab on this one, it's a good idea and as a alchemist I actually think this was already a side effect, but despite the lore being accepted, the one's pvping with it consistently arn't going to regard/care about this lore at all, and they're the people who use it the most. As far as a dev implementing it, the only thing I see possible on implementation would be slowness, going along with the hampered movement. But then again, I'm not a dev, so I'm probably wrong.
My two cents.
