Listen, I'm playing the game right now.
There is NO f2p elements. Let's take all the elements to explain to you what it is about:
Bravely Second is a new inclusion in the combat system, it's like a Joker. That Joker is totally optional and useless for the battles. It's pointless, and adds nothing to the battle system. It's just a temporary BONUS. It allows you to stop time for a moment to deal damage.
Now, if you're interested in that pointless, rushed bonus, you have two ways to use it:
Put your 3DS in sleep mode: Every 8 hours, you get 1SP so you can use it once.
Or, buy a SP drink to get 3SP.
The game won't bother you with this, it'll just tell you ONCE that you can use Bravely Second, and tell you can buy SP drinks if you want them fast. That's it and you'll never heard about this ever in the game. Not. a. single. word. Heck, Bravely Second isn't even displayed in the combat system. The game doesn't even told me how to activate it. I had to check all the buttons.
It's not about defending it, it's about stating facts. That's just NOT an excuse to skip this game, for a totally INVISIBLE feature likely made for really casuals people. And the game NEVER bother you with this. That's just a small feature which FIRST requires you to put your 3DS in sleep mode OR to buy points.
Now, if people want to boycott it for pseudo reasons, then do it. The only thing you'll succeed in doing is to show that West doesn't care about J-RPG. You want to show that you don't like microtransactions in your game ? Buy the game, don't use the microtransactions.
Seriously is not as bad as everyone it's making it look.
