I didn't have too much of a problem with Britt having Adelaide decide it was a better idea to kill the elves.  It wasn't ideal, but I was okay with this after giving it a little thought.  I however had a problem with Sena going out and yelling, very loudly, let's kill them all.  She failed a stealth roll, which was fine and to be expected, but you could have at least tried something else besides completely blowing our attempted ambush.  I also had a problem with Alec not bothering to even try to use the buff he was given and simply deciding to stumble out of cover before that.  Hence, we're going to end up dying no matter what characters we're using because half the party can't seem to be bothered to think.
