Something that might be a major problem with Yummi's W

So. I realize we still don't know a lot about Yummi, and hopefully the creators realized this flaw. But I sincerely hope that Yummi CANNOT auto attack when attached to an ally.

Reason being this, if they let her auto while connected then Yummi can literally build full AD and sit on a tank/diver and just destroy everything with no hope of being destroyed. And, if said ally does die, Yummi can just hop into the next soul.
