rU who exactly told you that w2w always took precedence over CBA, and how reliable are they? Do they have evidence? I know it doesn't really matter if it's true or not but as a passionate player of this game I am very curious.
I've played WA very actively since June 12th 1999, I remember my 1st game as if it were yesterday, I participated in many League Ropers since WACL and i've never experienced this, I certainly do not remember it being in any rulebook, perhaps it is possible it was an unwritten rule for some players? Would the WACL rules still be up somewhere, maybe that way back machine thing?
It doesn't even logically make sense which is why I can't understand why anyone would say it used to be like this, however back in 1999-2003 maps weren't as evil as they are now they were quite simple and most games would never reach SD.
