I drew the game. My last turn chance at a pass score was robbed by Animosity. To make it even more funny (=painful) was that I had forgotten to roll Animosity first, so I had made the 3+ pick up, interceptable 6+ pass and 4+ catch to a goblin (I was still due to make two Stunty dodges and one GFI without a reroll, but that's ok odds). After succeeding in those rolls I made the Animosity roll of 1.
So far (and not a bit influenced by the above) it's obvious that Animosity adds greatly to the problems with goblins. I'd be mad not to use my throwers for a pick up, if possible, and that means that I have to risk a hand off or pass to a goblin where I might need to burn a reroll on the Animosity when I really need it for the catch roll. This makes the goblins less useful to the team.
Based on this, I believe even more that Two Heads is a great first skill for the majority of Goblins (not that anyone's contesting this). Maybe I'll start developing the third one to skill up for TTM purposes. I think the first double could be Wrestle followed by Horns on the same player.
