Personally I would like other gold or fun-but-expensive options. Like 50mil is way too much for me, but I might blow 1 mil on a simple recolonization of some other mount (like a blue magitek reaper or green fat chocobo...something like that)

If they add some things between 1 and 5 mil that involve minions or mounts I might be all in. Even easier if they make sets of items ‘cause some people would “have” to buy all to complete their set.
