I'll re-iterate something I said before. This method helps prevent people from buying gil because people buy gil for various reasons.
They buy for:
1. To get carried through a fight (content)
2. Vanity Gear (because people often over price)(or the friendship headpiece)
3. Mounts (just buy a collector's edition ___ and get ___ in game!)
4. Minions (like the 10mil nutkins)
This can help circumvent some of this. Obviously they will keep on adding gear/vanity crafted as normal. (If they don't we wouldn't have known better anyways).
Another thing is, people are worrying too much. IF the time comes where they start making it F2P and Pay to Win model then stop playing. Odds are most people in here wouldn't hunt down these minions normally or be lucky enough to get a mount drop via EX primal farming.
Side note: The Cash Shop could help bring minions to people who don't want to buy the music CD... ect but just want the minion itself.
We have to pay for Eternal Bond as well but you don't see pitch forks being raised that much for that. Isn't that content that you have to pay for >_>?
