Most the threads I've read against RMAH have very few valid points if any.
That's similar to threads pro RMAH which I've read - very few had valid points if any.
But back to the topic I'd say that the division is more complex, I - for example - don't like RMAH but I'm ok with no skillpoints. And the rest is tl;dr.
