Battle results?

I'd like to dispute the exp and gold gained from black dragon raid. I myself have gotten 8000 points and i've observed that I only got 16k gold as a reward, and indeed 2 gold per point in general, but I cannot confirm the experience rate I suspect the individual who provided the info was under the influence of a raid crystal.

Also, if I am not mistaken, I believe the Attacker Role provides a maximum of 8500 total contribution points

A Raid Crystal gives you a 2nd experience value and a 2nd Gold Pouch, therefor, you don't even have to do calculations for the rewards.

then is it possible that the player who comes in first gets an extra bonus?
