no, the implication is that most vanila players are casuals. You got one game that is officially supported and developed catering to casuals and another that is ghetto backwods hack of an older version of a game that is propagandised against as illegal. Which audience is more likely to garner more simpletons? One version is gated by numerous things like selecting a private server. installing and then patching an old version of the game manually at that and is fearmongered against. On top of that it requires a dedication to the game prior to it, knowledge that there is such thing as private server as an option and will to go so far as to get the old version of the game because thats how much they want and like it over what retail did after cataclysm launch.
Ofcourse retailers are going to be a demographic that has way more kiddies morons and clueless casuals. Its not a slight against me even tho i play on retail, because i know generalisations can be made and that doesnt mean everyone in a group fits that, just the majority.
