Here's a stupid idea:

If SE is so sure that everyone LOVES the MW system why not put an AH counter at the golden bazaars?

Every AH could have a shared database and no complex new designs just the exact same system XI had with it's item limitations that all MW lovers seem to bring up.

I'm willing to bet real life money on this system becoming 1000 times more popular within a month and MW would die a natural death within months and nobody would miss it except that one guy who can't sell lvl5 gear for 40 000gil anymore.

Boohoo.
