As a disclaimer, I just picked those #s at random as an example. It is in your best interest to kill stuff together, the quicker a creature dies, the faster your point pool grows, and the more rolls you get based on that pool of points.Appreciate the info. So, in my scenario, if I joined in then he will get the same points for 1st position unless I somehow overtake his damage lead and take 1st position, which means he drops to 2nd. And under Kyronix example, the 2nd spot gets 3% less. But in the grand scheme of things, it seems it is better for the two of us to get a combined 27% for each kill (15% +12%) than for each of us to get 15% from half the kills. At least it seems that way. Even if one of the two warriors consistently got 1st position and the 15% each time, the 2nd person would benefit from getting 12% from twice the monsters.
It also is more fun to hunt together, because this way, afterwards when you are at the tavern enjoying some ale you can get into an argument over how big that Gibberling was and have a good ole fashioned tavern brawl!
