I'm ok with this anima system, it is pretty well balanced and the recovery rate is about right.

The only thing that really takes away from exploration, and that really annoys me, is that you can be teleported to places you've never been!

Seriously, the other day I was teleported to Mor Dhona to do some quest, and I thought it was just another zone, a purple one, but another place to go click on a "???" and hit return(chocobo music also removes a lot of great aspects this game has, but that's a whole different topic).
It wasn't until I had to walk there because I was out of anima that I really came to value it, and how hard it was to get there (from the black shroud).

And this is just an example. When I started I was teleported from limsa to windurst and uldah, and it felt cheap! I'm sure most players haven't even boarded the ferry.

I remember when I first reached San d'Oria, or my first jorney to Jeuno when I reached level 20, and I'll always remember that. That was exploration and adventure!

Conclusion:
I think it's great to teleport to wherever you want, as long as you've been there atleast once through walking!
