The difference between the two trinkets is estimated at a little over 1500 int, favoring BBoY but assuming no T15 2p. Not sure how the set bonus skews that result.
Yes, you missed out on an awesome trinket.
Yes, you would have seen a sizable increase to your dps.
Yes, you were the Good Guy Greg of your raid, and the lock owes you a beer.
Your raid is still be better than it was before, regardless of who got it. And you gain karma points to spend later on.
