It's not particuarly exclusive. The minions cost 2-3$, if you feel the minion isn't worth that much, then simply do-not purchase it.
The basic run-down is that these minions/mounts/services/semi-useless-vanity that they add is basically adding additional funding by cashing in on those with either a collectors bug, or a fickle choice of mind.
The EU servers being added before, on or after the expansion have been considered and finally finalised as a result of the extra income from the vanity/services they've added.
Fantasias, Retainers, Name Changing and Vanity Items were ALL requested by players from 1.0 and 2.0.
The forum archive proves this, (obviously not everyone was pro-vanity items, but the pro's of adding it out-weight the simply con of "I don't want to pay for it")
I would be vehlemtly against vanity items in the Mog Station if it out weighed the benefits of extra content in-game as a result.
If a few low-production minions, mounts and old seasonal items along with essential MMO services gets new content, new datacentres and more. Then it's worth it.
Yes. Minions that were commissioned by the development team to be made FOR the mogstation. The minions have a very very low production time and cost, therefore it's easy to produce a wide variety of them without having a major impact on overall development time, costs or the game client itself.
Yes, it's frustrating for some that "They'll just keep adding more", I completely understand why they're furstrated. But that doesn't mean they're going to stop adding things into the game, they'll simply add and make things specifically for the mogstation as a way to make some extra money along side subscriptions.
The world isn't fair, and you can't have everything that you want. But in this case you can, you just have to fork over the premium they're asking for.
Customers request EU datacentre, SE oblige.
EU datacentre will cost hundreds of thousands of dollars to setup and maintain.
Extra revenue is required in order to balance out profit, development costs and further expansion of the game.
Developers look for alternative ways to earn extra money beside subscriptions.
Datacentres are very, very expensive and take months of preparation to setup a network cluster whilst maintaining a certain quality and standard required for an MMO datacentre to prove functional, this is not cheap.
As a result, they're going to need extra money to procure the finances for a third datacentre, and therefore optional basic items that have no real impact on the game as the best choice without offending players by adding in "Pay to win" progression additions.
INB4 "But subscriptions", the profits from this are torn apart and thrown all across the board at Square Enix into the development of other titles and endeavours.
