Then it goes back to my original point, even if you can do it, it's more work still.
Go out and establish new connections for endgame is more work. Paying people is more work because gil takes time to get. So if one person already have connections to do endgame without having to pay/make new friends, he'd need to work harder on Asura.
The fact is, Asura isn't as magical as you claimed, immigrants still have to work hard for it, make new friends, establish new connections with LS, compromise and gear/lv up certain high demand jobs to get a chance for magic to come true, and that takes time. If one individual(not me, I'm not a super established player) already has the connection/ls for hard stuff without having to put more hours on gear/job/connections on NotAsura server then he simply aren't going to do better on Asura without more work.
Most if not all the people that transferred to Asura and ended up did better are people that don't have group/ls/friends to get things done on their original servers, they had no choice but leave. Of course situations will improve because they're already in a very bad position before transfer. And that's probably the "magic" that you're talking about.
But if a player that's already established, then transferring just isn't a good choice for them. More like wasting $18
Either way, people with common sense woulda know that your claim about Asura magic story aren't all real, more like 80% real, but not 100% real. If there's a sales position in FFXI, you'd probably be top sales.
