Going to get a tf2 server on day anyway, prolly under the DOA name.
DOA is and always will be a CS clan, but we would also have a tf2 server AND people wouldn't be able to join DOA unless they play on the CS servers.
Can't see any reason for not being able to scrim tf2 under DOA.
Me being a leader of DOA I can't use any other clan tag in my friends list.
Tried in once when I was in AaC (tf2 clan) while in DOA, it was a pain in the ass.
Tho tf2 scrims or fucking awesome, need at least 8 a side tho.
So nope, I will only ever use the DOA tag.
That's my 5cents worth.
