Let's scale this up a bit. Say there's a group of 7 friends who shout for an 8th and you join their hamlet party. Only 1 of the people in the group of 7 needs a seal, and the other 6 are helping him out. Do you deserve 50% of all seal drops even though you're contributing 1/7th as much as they are? And how is that party any different to you than if you joined a party of 8 individuals who all needed seals for themselves? Why does it matter to you?

You lost a fair roll that you knew the odds on in advance. The fact that the winner passed his reward to his friend doesn't change the fact that he contributed to the hamlet and is just as entitled to a reward as anyone else.
