I was the founder of Savage Alliance, and the first guild to leave it due to the very reason you mentioned... it was a massive skillless furry alliance.. I still own the website name if i remember right. Everyone makes mistakes.... but it was only for a short time. a minor blemish on an otherwise good record. After the first DF, we were only ever part of smaller, more focused alliances.
I remember almost everyone who joined my guild.. Unless you joined in DF:UW.. I don't remember you. On a side note, I never once thought shield walls were a good idea in DF nor did anyone in ATS, and never once used that tactic outside of CRPG:) you are mistaken.
