Other than playing with changing itinerary or code-shares (presumably) and operating carriers btw the points, I don't see what travel agents can add that AA RTW desk can't.
AA requires at least one overwarter segment to be an AA flight which may be undesirable to some people here, they also will not book an AA operated flight with the code of another oneworld member. It sounds like they also charge higher YQ/YR for many flights than an independent travel agent would plating on Qatar ticket stock.
