I agree. Either make the fight a 2v1 with your support on auto or make it so the plundering player keeps the damage between teams. Just like on my server, the highest BP person in our group is rated #2 on the server, but our rival group has 3 out of 4 people in top 4. So your server rank 2 member can only assist you 3 times a day and then there is no chance of fighting off plunderers for the rest of the day.
