Sorry but there is nothing challenging about Realism, it's a mod for people that simple can't aim properly. Goto any realism clan server and u will simply see 80% of the people camping with STG's. Go to a clan default server and u will see skillful players that are excellent shots.
Why do you think realism players suck on default servers, yet default players own on realism servers?
Simple thing is that realism is for noobs that don't take it too serious. Default is for the pros. If I were wrong, why are all the best MOH players default clan members?
I have a feeling that many of the top MOH players will drop MOH altogether after this very poor showing from Breakout and start playing COD (providing Multi is cool)
