Reaiming mobs in combat

A Talshidar throws a mountain goat to the ground with stunning force. A Talshidar starts aiming at you! You dodge a Talshidar's pierce. A Talshidar's pierce is unable to penetrate a polished mithril girth. Extending your arm through his throw, a Talshidar strikes hard to your ribs! A Talshidar's ground control DISMEMBERS you! throw damage doesn't go through at all but somehow he throws my goat and ground controls me.
