There were a few of you, including you Noldorin that complained in the previous thread when Rio joined in the war against the northern. Correct me if i am wrong.
From what I remember there was considerable discussions about the "even-ness" of the war in numbers. Aside from that there was indeed my comment on not liking Riombaras IG reasons for war, as in that they didn't bother to come up with actual reasons instead of just joining (though getting them into the war was the goal from all sides).
Its the only things I can remember/find, but might have missed something.
