I'm sorry I never played planetside so I do not know what the comparison is.
People are not buying gold to do this now? the 496 is the only things that would actually costs you anything more than a server xfr.
How many elite guilds are there with that set of requirements? If they require something then they do it cuz they enjoy being super hardcore. How does that affect you? In most cases they will do things with less because their skills are top notch. Adding RMAH will not do anything to effect their recruitment process.
Like I said its something I would want but we will probably never get. I'm fine with it. I've been playing since vanilla nothing surprises me with the changes they make or features they add. I'm sure Blizz has done enough market research to know its player demographic by now.
