We lost a guardian, and 2 battleships, I think a tempest, and a tempest naval/fleet? issue. In all, we came out about 800mill ahead in the win/loss ratio, as we took a rook, and a falcon down in the fleet that jumpped us while we were warping away.
If our full fleet was there we would have beaten the guys who attacked at the end (and would have had another carrier kill, as they didn't have enough support with him at the time, and were relying on the 2 falcons to keep our DPS down, but we killed one of them fast, which really negated their advantage). But it really depends on if they had others ready to hot-drop in on us, as the carrier was local/cloaked which came in on us.
Hard to really say. Really the problem was our fleet setup as the main FC couldn't fleet warp everyone, only his wing, which left a smaller second wing delayed in warping off, and those were the guys who got caught (mostly, I was in that second wing, but manually warped when he said to warp, I guess they were not ready for some unknown reason, possibly not aligned, even though we were told to align 30 seconds before).
