I havent experienced any issues yet with the raid cap, but IMHO no group (be it 36 or 6) should be able to jeopardize a zone - the raid mobs at a given time, yes, but the not the entire zone. Nevertheless, I think 42 man cap is great - to allow the odd exp group to enjoy a zone while other guilds raid with 36. However, I suggest asking whatever you want done in a mature manner that pertains solely to the matter at hand - throwing down disrespectful lines just for the hell of it wont accomplish anything.
