The only thing that scares me with the “Most damage” gets the prize is on the final Boss Mob. I can see someone pulling in 60 dragons at the end to get the rare drop if there is one. As long as the “most damage” gets the boss platinum (and only the platinum) and the rare is still luck of the draw, it should be fine.

Damage on the boss does not determine who gets the rare, damage over the entire invasion does. It is a random person in the top 3 of the leader list that pops up at the end.

Technically this is incorrect, since you can do piddly squat damage and still easily top 3.  Its based on score, not damage dealt.
