Embarrassing? Not in the least.
I would be more embarrassed to be in a group which lies to their enemies about being friends before attacking. I would find it more embarrassing to be in a group which uses plants to steal artefacts. I would find it more embarrassing to be in a group which describes itself as Ultimate Warriors. All of these things, they are ok, but I don't think Goats have much to be embarrassed about when contrasted with 'dirty' tactics used elsewhere.
Just when I thought you have gotten yourselves together after the backstab incident, you pull it out from your sleeve again. How delightful. That's also the only point relevant to us, remaining two concern GUNNERS and them only and I do agree with you on those.
And as a side note, I don't think anyone has called the process of zerging dirty by any means. Quite the contrary, if everyone were honest and straightforward about it happening.
