You can be 6.4 gs but still in need of EOF, so you are bound to green noobs when you que RDF.
Problem is not these green nobs themselves but their game attitude - they are not prepared, they perform ****, their game knowledge is ****. Most of em do not have reagents for buff and do not buff at all.
Most of them have brainded spec and gems (even lowbie ones), they do not want minmax still get offended every time some1 points this out.
Not having 5man encounters knowledge in the INTERNET AGE is a crap excuse, speaks about player a lot - garbage who does not want to not be garbage for team mates , however wants to be carried to the shiny future.
If you do not like current Icecrown community, you can travel to roleplaying realm named Lordaeron and play there - due to low online this realm is more like solo RPG than MMORGP, so you won't meet much toxic players there. You wont meet much players there in general.
